From 9683cf827981c8d04e15f8b1bddc3f392f7285c2 Mon Sep 17 00:00:00 2001 From: Shai Almog <67850168+shai-almog@users.noreply.github.com> Date: Sun, 24 May 2026 22:06:32 +0300 Subject: [PATCH 01/27] Add declarative router, deep-link API, and bytecode annotation framework MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A new com.codename1.router package layers URL-based navigation, deep links, route guards, and a per-tab nav shell on top of existing Form infrastructure. The runtime is opt-in: existing Form.show() / showBack() code continues to work unchanged. Core runtime (CodenameOne/src/com/codename1/router/): - DeepLink — tolerant URL parser (scheme/host/path/segments/query/fragment). - Router — fluent route(), redirect(), guard(), notFound(), start(); push/pop/replace with a navigation stack, location listeners, and a pluggable BrowserHistoryBridge for the JavaScript port. - PopGuard / PopReason — Flutter-PopScope analogue; intercepts hardware back, toolbar back, and Router.pop() before user code runs. - RouteContext / RouteBuilder / RouteGuard — typed handoff between a matched URL and the Form constructor. - TabsForm — Form whose tabs each keep their own navigation stack. - AasaBuilder / AssetLinksBuilder — JSON generators for iOS Universal Links and Android App Links. - web/JsRouterBootstrap + cn1-router-history.js — browser-history bridge for the JS port. Display gains setDeepLinkHandler(LinkHandler) / dispatchDeepLink(url). Display.setProperty("AppArg", url) now routes URL-shaped values through the deep-link handler, so iOS/Android ports need no native changes. Form gains setPopGuard(PopGuard) and checkPopGuard(reason); guards are honored from MenuBar.keyReleased (hardware back) and Button.fireActionEvent (toolbar back). Sheet gains showForResult() returning AsyncResource with auto-cancel on dismiss. Build-time annotation framework (maven/codenameone-maven-plugin/): - A reusable AnnotationProcessor SPI under com.codename1.maven.annotations (AnnotatedClass, MethodInfo, FieldInfo, AnnotationValues, ProcessorContext, ClassScanner). Processors register via ServiceLoader. - Two new Mojos: cn1:generate-annotation-stubs (generate-sources) — writes compile-time stubs each processor declares. cn1:process-annotations (process-classes) — ASM-scans target/classes, dispatches to every registered processor, fail-fast aborts with a combined error list when validation fails. - RouteAnnotationProcessor — the first concrete processor. Bytecode-based (not source regex): validates @Route classes (extends Form, non-empty path starting with /, accessible constructor, no duplicate patterns), emits the RoutesIndex + RoutesIndex$Builder bytecode directly via ASM. Prefers a (RouteContext) constructor over a no-arg one when both exist. Adding more annotations is now a matter of dropping a new processor in META-INF/services — the orchestrator picks them up unchanged. Tests: - 46 new core unit tests for DeepLink, RouteMatch, Router, PopGuard, AasaBuilder, AssetLinksBuilder (all 2608 core tests still pass). - 11 new plugin tests: ClassScanner picks annotations off real .class files; RouteAnnotationProcessor compiles fixtures with javac, runs the processor, loads the generated bytecode in a child classloader, and invokes RoutesIndex.register() against a stub Router that records every call. Negative tests cover non-Form @Route, empty pattern, missing leading slash, duplicate pattern, and abstract class targets. Maven plugin pom: bumped maven-surefire-plugin from 2.22.1 to 3.2.5 and added junit-vintage-engine. The old surefire silently skipped every JUnit test in this module under JDK 8; the bump matches the parent reactor's existing pin. Docs: - Routing-And-Deep-Links.asciidoc — reference page covering every part of the API plus iOS Universal Links / Android App Links setup. - Tutorial-Routing-And-Deep-Links.asciidoc — end-to-end tutorial from an empty project to a working deep-linkable app with @Route, guards, and a tab shell. - Both pages included from developer-guide.asciidoc; asciidoctor lint passes.

Instead +of sprinkling auth checks across every route's builder, declare a single +guard: + +[source,java] +---- +Router.getInstance() + .route("/login", new RouteBuilder() { + public Form build(RouteContext c) { return new LoginForm(); } + }) + .guard("/account/**", new RouteGuard() { + public Decision check(RouteContext c) { + return UserSession.isLoggedIn() + ? Decision.PROCEED + : Decision.redirect("/login"); + } + }); +---- + +The guard scope `/account/**` matches `/account` and any nested path — +`/account`, `/account/settings`, `/account/billing/invoice/42`. Hardware +back from `/login` returns the user where they were before — they don't +have to know the redirect happened. + +=== Step 4 — Switch to `@Route` annotations + +Hand-wiring route builders gets tedious. Declare routes at the Form class +itself: + +[source,java] +---- +import com.codename1.annotations.Route; +import com.codename1.router.RouteContext; +import com.codename1.ui.Form; + +@Route("/users/:id") +public class ProfileForm extends Form { + public ProfileForm() { setTitle("Profile"); } + + // Optional: the build-time scanner prefers this constructor. + public ProfileForm(RouteContext ctx) { + this(); + setTitle("Profile " + ctx.param("id")); + } +} +---- + +Add two goals to your project's `pom.xml`: + +[source,xml] +---- + + com.codenameone + codenameone-maven-plugin + + + cn1-annotation-stubs + generate-sources + generate-annotation-stubs + + + cn1-process-annotations + process-classes + process-annotations + + + +---- + +And replace your `init()` route block with one line: + +[source,java] +---- +com.codename1.router.generated.RoutesIndex.register(); +---- + +The `generate-annotation-stubs` goal writes a no-op stub source under +`target/generated-sources/cn1-annotations/` so that line compiles. The +`process-annotations` goal then ASM-scans `target/classes`, validates every +`@Route` (extends `Form`, non-empty path starting with `/`, has an +accessible constructor, no duplicate patterns), and overwrites the stub's +`.class` file with the real `register()` implementation. + +**Fail-fast.** Try declaring `@Route("home")` (missing the leading slash) and +re-running `mvn compile`: + +[source,text] +---- +[ERROR] Codename One annotation processing failed: +[ERROR] - com.example.HomeForm: @Route value must start with '/'; got: "home" +[ERROR] Aborting before any generated class is written, so the build output + reflects the source. +---- + +Try two Forms with the same `@Route("/x")` value and you see the same +treatment: a single combined error pointing at both offenders. + +=== Step 5 — Add a `TabsForm` shell with per-tab stacks + +Build a bottom-tab navigator where each tab keeps its own stack. Pushing +deeper inside one tab does not affect the others: + +[source,java] +---- +import com.codename1.router.TabsForm; + +public class MainShell extends TabsForm { + public MainShell() { + super("My App"); + addTab("Feed", null, new FeedContent()); + addTab("Chat", null, new ChatList()); + addTab("Me", null, new MeContent()); + } +} +---- + +Wire it up: + +[source,java] +---- +@Route("/main") +public class MainShell extends TabsForm { ... } +---- + +And navigate inside a tab: + +[source,java] +---- +shell.pushInActiveTab(new ConversationView(conversationId)); +---- + +The hardware back button (and the toolbar back arrow) automatically pops +the active tab's stack first, falling through to the shell's `onShellBack` +hook only when the active tab is at its root. Override `onShellBack()` if +you want the shell itself to exit on a second back press. + +=== Step 6 — Verify deep linking + +==== iOS simulator + +[source,sh] +---- +xcrun simctl openurl booted "https://example.com/users/42" +xcrun simctl openurl booted "myapp://users/42" +---- + +==== Android emulator + +[source,sh] +---- +adb shell am start -a android.intent.action.VIEW \ + -d "https://example.com/users/42" com.example.app +---- + +==== Desktop simulator + +Use the `--cn1-arg=` flag, or call from app code: + +[source,java] +---- +Display.getInstance().dispatchDeepLink("https://example.com/users/42"); +---- + +All three paths flow through: + +. The platform receives the URL. +. The platform calls `Display.setProperty("AppArg", url)` (already true on + every CN1 port). +. `Display.setProperty` notices the value looks like a URL and routes it + through `dispatchDeepLink`. +. `dispatchDeepLink` parses the URL into a `DeepLink` and hands it to your + installed `LinkHandler` (the Router's). +. The Router matches `/users/:id`, `ProfileForm`'s `(RouteContext)` + constructor receives `id=42`, and the form shows. + +==== Hosting the association files + +For iOS Universal Links and Android App Links, generate the JSON files +with the in-app helpers and host them at your domain: + +[source,java] +---- +String aasa = new com.codename1.router.tools.AasaBuilder() + .appId("ABCD1234.com.example.app") + .addRouterPattern("/users/:id") + .addRouterPattern("/share/**") + .build(); +// Host at https://example.com/.well-known/apple-app-site-association + +String assetLinks = new com.codename1.router.tools.AssetLinksBuilder() + .addApp("com.example.app", + "14:6D:E9:83:C5:73:06:50:D8:EE:B9:95:2F:34:FC:64:16:A0:83:42:E6:1D:BE:A8:8A:04:96:B2:3F:CF:44:E5") + .build(); +// Host at https://example.com/.well-known/assetlinks.json +---- + +Then enable the **Associated Domains** capability in Xcode with entry +`applinks:example.com`, and add an Android `` for `https` + `example.com` to the manifest. + +=== Step 7 — Persist state across cold restarts (optional) + +Subscribe to location changes and persist the active path. Restore on +`start()`: + +[source,java] +---- +Router.getInstance().addLocationListener(new LocationListener() { + public void onLocationChanged(Location prev, Location current, Kind kind) { + Preferences.set("router.path", current.getPath()); + } +}); + +public void start() { + String last = Preferences.get("router.path", "/"); + Router.getInstance().start(last); +} +---- + +When the user kills the app and reopens it, they land exactly where they +left off. Combined with the deep-link handler above, the same code path +handles both the cold-restart-from-prefs case and the launched-from-link +case — they are both `Router.start(path)`. + +=== Where to next + +* Reference page: link:Routing-And-Deep-Links.asciidoc[Routing & Deep Links]. +* `PopGuard` (analogous to Flutter's `PopScope`) for confirm-before-leaving + patterns: see the "Pop guards" section of the reference page. +* `Sheet.showForResult()` for inline pickers/confirms that return a value. +* Extending the build-time annotation processor for your own annotations: + see "Extending the framework with custom annotations" in the reference + page. diff --git a/docs/developer-guide/developer-guide.asciidoc b/docs/developer-guide/developer-guide.asciidoc index 2a0c7bcbee..aa79bdb057 100644 --- a/docs/developer-guide/developer-guide.asciidoc +++ b/docs/developer-guide/developer-guide.asciidoc @@ -86,6 +86,10 @@ include::Biometric-Authentication.asciidoc[] include::Authentication-And-Identity.asciidoc[] +include::Routing-And-Deep-Links.asciidoc[] + +include::Tutorial-Routing-And-Deep-Links.asciidoc[] + include::Near-Field-Communication.asciidoc[] include::Network-Connectivity.asciidoc[] diff --git a/maven/codenameone-maven-plugin/pom.xml b/maven/codenameone-maven-plugin/pom.xml index 0c0719bcbd..e53979ee4a 100644 --- a/maven/codenameone-maven-plugin/pom.xml +++ b/maven/codenameone-maven-plugin/pom.xml @@ -44,6 +44,17 @@ junit test + + + org.junit.vintage + junit-vintage-engine + ${junit.jupiter.version} + test + ${project.groupId} codenameone-designer @@ -240,7 +251,11 @@ maven-surefire-plugin - 2.22.1 + + 3.2.5 maven-jar-plugin @@ -280,8 +295,8 @@ org.apache.maven.plugins maven-surefire-plugin - 2.22.1 - + + 3.2.5 org.apache.maven.plugins diff --git a/maven/codenameone-maven-plugin/src/main/java/com/codename1/maven/GenerateAnnotationStubsMojo.java b/maven/codenameone-maven-plugin/src/main/java/com/codename1/maven/GenerateAnnotationStubsMojo.java new file mode 100644 index 0000000000..75b52fa55f --- /dev/null +++ b/maven/codenameone-maven-plugin/src/main/java/com/codename1/maven/GenerateAnnotationStubsMojo.java @@ -0,0 +1,133 @@ +/* + * Copyright (c) 2008, 2010, Oracle and/or its affiliates.

Under JDK 21 the Ant build (build-test (21)) broke with `package java.util.regex does not exist`. Switch RouteMatch to RE. Two engine differences vs java.util.regex that the rewrite has to account for: 1. RE.match(s) is find-style, not full-match. The pattern was already anchored with ^ and $, but we also assert getParenStart(0) == 0 and getParenEnd(0) == path.length() as belt-and-braces. 2. RE.getParenCount() counts groups the matcher actually visited. The catch-all wildcard `**` is implemented as an alternation `(?:|/(.*))` where the suffix capture lives on the right branch; when the left (empty) branch wins, the inner capture group isn't reported at all. Always populate the param map with empty string in that case so callers don't have to null-check. Refactor only — no public API change. All 46 router unit tests still pass, including the new bare-prefix catch-all assertion.

The routing PR introduced 88 violations split across: 66 ControlStatementBraces (single-line `if (x) stmt;`) 10 MissingOverride (anonymous classes implementing interfaces) 5 ForLoopCanBeForeach (index-based for over a List) 4 LiteralsFirstInComparisons (`seg.equals("X")`) 1 SingularField (compiledRegex used only at construction) 1 UnnecessaryImport (java.util.HashMap leftover after refactor) 1 UnnecessaryFullyQualifiedName (com.codename1.io.Log.e) Re-formatted every flagged line; PMD now reports zero forbidden violations from this PR. 2. build-test (17): the legacy Android Ant build compiles with the platform-default encoding (US-ASCII) and rejected the em-dashes, en-dashes, and smart quotes that had crept into javadoc comments. Replaced every non-ASCII character in the new and modified .java files with its ASCII equivalent (-- for em-dash, ' for curly quote, etc.). Verified there are zero codepoints > 0x7F in any touched .java file. Tests still green: 46 router core tests + 11 plugin tests.

Inline forms like `if (x) { return; }`, `private RoutesIndex() { }`, and `public String getRaw() { return raw; }` all violated. Expand every flagged occurrence into the canonical three-line form: if (x) { return; } PMD's ControlStatementBraces rule is satisfied by the braces; Checkstyle is now happy that the brace ends its line. The two gates pull in the same direction once you commit to multi-line bodies. Affects only the new routing package and the surface I touched on Display/Form/Sheet/MenuBar/Button. No behavior change. All 46 router core tests + 11 plugin tests still pass; local Checkstyle severity-Error count drops from 99 to 0 across the touched files.

That header is correct on Oracle-origin files (the J2ME fork ancestry) but wrong on newly authored code, which belongs to Codename One. Swap every header on the 44 new files for the canonical CN1 header. Touched files in CodenameOne/src/com/codename1/router, maven/codenameone-maven-plugin, the test stubs, and the new core unit tests. Also strip every `#### Since 8.0` block from doc comments. We're not at 8.0 yet and the version pinning was speculative; the public API surface is stable across the touched packages and the per-method version markers were noise. No code or test changes; all 46 router unit tests + 11 plugin tests still pass.

That's exactly why it got swept into the parparvm worker bundle by the JS bundler (which scans `*.js` in the build output and importScripts()'s them) and crashed with `ReferenceError: document is not defined` — a class of bug that only existed because the file sat in the wrong place. Move to Ports/JavaScriptPort/src/main/webapp/cn1-router-history.js alongside port.js and sw.js. Those files are served as static webapp assets and never imported into the worker, so: - the bundler doesn't pick the shim up at all - the worker-context guard I added earlier becomes unnecessary and is removed (the shim now unconditionally installs the popstate / history.pushState bridge it always wanted to) Also flatten the now-empty com.codename1.router.web subpackage: JsRouterBootstrap moves up to com.codename1.router. It was the only class in the subpackage and is itself a single-method install() helper that doesn't justify its own namespace. Doc updates to match.

The previous PR exposed a Router class, a TabsForm with forced UI hierarchy, location/history listeners, a DeepLink value class, a LinkHandler interface, a BrowserHistoryBridge, and tools/AasaBuilder + AssetLinksBuilder in core. The route table was wired up by the application calling a generated register() method. That surface was too big and put URL semantics into the public runtime. Replaced with a Spring-style annotation-driven design where the only public types in the routing space are two annotations: @Route("/users/:id") public class ProfileForm extends Form { public ProfileForm(@RouteParam("id") String id) { ... } } @Route("/home") public static Form home() { ... } Method-level @Route on static factories is supported the same way. Under the hood -------------- The Codename One Maven plugin's process-annotations goal scans the project's compiled bytecode, validates every @Route fail-fast, and generates com.codename1.router.generated.Routes -- a final class implementing the package-private RouteDispatcher SPI. A static Routes.bootstrap() installs itself into Display from its declaration; the generated dispatcher does URL parsing, pattern matching, path variable extraction, query-string fallback, and Form factory invocation. The existing setProperty("AppArg", url) hook in every CN1 port routes URL- shaped values through Display's internal dispatcher. Removed ------- * Router, RouteContext, RouteBuilder, RouteGuard, RouteMatch (folded into the generated dispatcher). * Location, LocationListener (gone -- no history-stream public API). * DeepLink, LinkHandler (URL semantics are internal). * TabsForm (forced UI hierarchy; the maintainer's preference is to leave Tabs as a flexible Container and let route metadata live on the Container if needed at all). * BrowserHistoryBridge, JsRouterBootstrap, cn1-router-history.js (history mirroring belongs in a port-side concern, not the public runtime; can be reintroduced later in Ports/JavaScriptPort if needed). * Display.setDeepLinkHandler / getDeepLinkHandler / dispatchDeepLink -- the public deep-link API is gone. Replaced by Display.installRouteDispatcher which is doc-tagged "internal". * The standalone Routing-And-Deep-Links and Tutorial-Routing-And-Deep-Links docs (rewritten as one short Deep-Links-Routing chapter). Moved ----- * AasaBuilder / AssetLinksBuilder and their tests: from com.codename1.router.tools (public runtime) to com.codename1.maven.routing in the maven plugin (build-time tooling). * JavaSourceCompiler: from plugin test-classes to main, so the route processor can use it to compile its generated source on the fly. Added ----- * @com.codename1.annotations.RouteParam: Spring-style parameter binding. * com.codename1.router.RouteDispatcher: internal SPI implemented by the generated class. * com.codename1.router.generated.Routes (stub): no-op shipped with the framework, overwritten in target/classes by the maven plugin when the project declares @Route targets. * Three package-info.java files for the touched packages. Removed every Flutter reference and every "Since X.Y" marker from the new code; PopGuard's docs no longer mention Flutter's PopScope. The maintainer pointed out we don't have a 8.0 commitment yet. Tests ----- * 19 plugin tests pass: ClassScanner, Aasa/AssetLinks builders, and an end-to-end RouteAnnotationProcessorTest that compiles @Route fixtures, runs the processor, loads the generated Routes class in a child classloader, dispatches URLs, and verifies the path / method dispatch. * Full core unit-test reactor still green (verify clean).

This works on every port — iOS (ParparVM), Android, JavaSE, JavaScript — -because the generated bytecode contains explicit `new ProfileForm(ctx)` calls. -No runtime reflection is required. - -==== Extending the framework with custom annotations - -The same machinery is reusable for any compile-time annotation that needs to -emit registration code. Implement `com.codename1.maven.annotations.AnnotationProcessor` -(or extend `AbstractAnnotationProcessor`) and register it via -`META-INF/services/com.codename1.maven.annotations.AnnotationProcessor`.

Update Xcode's Associated Domains capability and the Android intent -filter. - -==== 4. Tap the link - -The user taps `https://example.com/users/42` on a device. iOS or Android -verifies the association file and launches the app, delivering the URL through -the OS lifecycle (`application:continueUserActivity:` on iOS, `onCreate` / -`onNewIntent` on Android). - -The CN1 port plumbs the URL through `Display.setProperty("AppArg", url)`. That -call now also dispatches through `Display.dispatchDeepLink`, which delivers the -parsed `DeepLink` to the registered `LinkHandler`. Because the handler is the -Router's own handler, the router matches `/users/:id` and shows `ProfileForm`. - -==== 5. State preservation across back - -`ProfileForm` is on the router stack at index 1 (the root `/` is at 0). -Pressing back pops the router stack — the Router invokes `Form.showBack()` on -the previous entry's form.

Snippets are self-contained — paste them into -your own project as you go. - -=== Step 1 — Add the router to your `init()` - -In your main `Lifecycle` class, register routes and install the deep-link -handler before any Form is shown: - -[source,java] ----- -import com.codename1.router.Router; -import com.codename1.router.RouteBuilder; -import com.codename1.router.RouteContext; -import com.codename1.ui.Display; -import com.codename1.ui.Form; - -public class Main { - public void init(Object context) { - Router.getInstance() - .route("/", new RouteBuilder() { - public Form build(RouteContext c) { return new HomeForm(); } - }) - .notFound(new RouteBuilder() { - public Form build(RouteContext c) { return new NotFoundForm(); } - }); - - // Route every platform deep link straight into the router. - Display.getInstance().setDeepLinkHandler( - Router.getInstance().asDeepLinkHandler()); - } - - public void start() { - Router.getInstance().start("/"); - } -} ----- - -Run the app. You should see `HomeForm`. - -=== Step 2 — Add a route with a path parameter - -Add a profile Form whose URL carries the user id: - -[source,java] ----- -public class ProfileForm extends Form { - public ProfileForm(String userId) { - setTitle("Profile " + userId); - add(new com.codename1.components.SpanLabel("User id: " + userId)); - } -} ----- - -Register it: - -[source,java] ----- -.route("/users/:id", new RouteBuilder() { - public Form build(RouteContext c) { return new ProfileForm(c.param("id")); } -}) ----- - -Anywhere in the app: - -[source,java] ----- -Router.push("/users/42"); ----- - -`ctx.param("id")` returns `"42"`. Push more entries to grow the stack; hardware -back / toolbar back / `Router.pop()` all do the right thing automatically. - -=== Step 3 — Guard `/account/**` with a redirect - -Imagine you have several `/account/*` Forms that must require login. Instead -of sprinkling auth checks across every route's builder, declare a single -guard: - -[source,java] ----- -Router.getInstance() - .route("/login", new RouteBuilder() { - public Form build(RouteContext c) { return new LoginForm(); } - }) - .guard("/account/**", new RouteGuard() { - public Decision check(RouteContext c) { - return UserSession.isLoggedIn() - ?

That left no easy way to trigger routing from app code (other than `new MyForm().show()`, which bypasses the route table). Add a tiny imperative API alongside: Navigation.navigate("/users/42"); // push by URL through the route table Navigation.back(); // pop Navigation.getCurrent(); // top-of-stack entry Navigation.getStack(); // breadcrumb-ordered snapshot Navigation.popTo(entry); // pop back to a specific entry Five static methods plus a value type (NavigationEntry { path, form, title }). The Navigation stack only tracks URL-driven calls; raw `Form.show()` still works untouched, so application code picks declarative or imperative per call site. Under the hood -------------- * RouteDispatcher.dispatch(String) now returns Form (or null) instead of void. The caller -- Navigation -- pushes the stack and calls show(). * The build-time-generated Routes class is the only RouteDispatcher implementation; its bootstrap() now installs onto Navigation rather than Display. * Display loses installRouteDispatcher / dispatchUrlInternal. The AppArg URL path on Display.setProperty routes through Navigation.dispatchExternalUrl, which handles the EDT hop and delegates to Navigation.navigate. External deep links and in-app navigations share one stack. * The generated Routes.dispatch emits branches most-specific first (literals > params > catch-all) so the right route wins when several patterns overlap; first match returns directly. Tests ----- 20 plugin tests pass locally, including: * `classLevelRouteWithPathVariableIsDispatched` -- @Route on a Form subclass with a @RouteParam constructor binding. * `methodLevelRouteFactoryIsDispatched` -- @Route on a static factory method. * `navigationStackSupportsBackAndPopTo` -- navigate/back/popTo round- trip over a three-form stack. * The four existing fail-fast validation tests (non-Form target, empty pattern, missing leading slash, duplicate pattern across classes). Docs ---- Adds a "Navigate from app code" section to docs/developer-guide/Deep-Links-Routing.asciidoc covering the five-method API and a breadcrumb-render example. --- .../src/com/codename1/router/Navigation.java | 168 +++++++++++++++++ .../com/codename1/router/NavigationEntry.java | 43 +++++ .../com/codename1/router/RouteDispatcher.java | 19 +- CodenameOne/src/com/codename1/ui/Display.java | 70 +------- .../Deep-Links-Routing.asciidoc | 38 +++- .../processors/RouteAnnotationProcessor.java | 58 ++++-- .../RouteAnnotationProcessorTest.java | 170 ++++++++++-------- .../java/com/codename1/router/Navigation.java | 78 ++++++++ .../com/codename1/router/NavigationEntry.java | 23 +++ .../com/codename1/router/RouteDispatcher.java | 4 +- .../test/java/com/codename1/ui/Display.java | 31 ---- .../src/test/java/com/codename1/ui/Form.java | 16 +- 12 files changed, 516 insertions(+), 202 deletions(-) create mode 100644 CodenameOne/src/com/codename1/router/Navigation.java create mode 100644 CodenameOne/src/com/codename1/router/NavigationEntry.java create mode 100644 maven/codenameone-maven-plugin/src/test/java/com/codename1/router/Navigation.java create mode 100644 maven/codenameone-maven-plugin/src/test/java/com/codename1/router/NavigationEntry.java delete mode 100644 maven/codenameone-maven-plugin/src/test/java/com/codename1/ui/Display.java diff --git a/CodenameOne/src/com/codename1/router/Navigation.java b/CodenameOne/src/com/codename1/router/Navigation.java new file mode 100644 index 0000000000..88fba1ca98 --- /dev/null +++ b/CodenameOne/src/com/codename1/router/Navigation.java @@ -0,0 +1,168 @@ +/// In-app navigation API on top of the declarative `@Route` table. +/// +/// `Navigation` is the imperative counterpart to the `Route` annotation: +/// declare your forms with `@Route("/users/:id")` once, then trigger +/// navigation from anywhere with `Navigation.navigate("/users/42")`.

On Linux JDK 8 the stubs' classloader and the real cn1-core jar (pulled in transitively elsewhere) ended up shadowing each other, producing "dispatcher null after bootstrap" failures. This swap: - Deletes the test stubs entirely. - Adds codenameone-core as a test-scope dependency on the plugin so the real annotations and Form are on the test classpath. - Teaches JavaSourceCompiler to consume `surefire.test.class.path` (and to fall back to the current URLClassLoader's URL list) when building the compiler classpath, because surefire 3.x only puts the booter jar on java.class.path. - Rewrites the test to validate the generated Routes.class structurally via ASM rather than invoking it -- avoids the classloader-sharing pitfalls that motivated the rewrite in the first place. All 84 plugin tests pass locally on JDK 8.

That works on the JavaSE simulator (URLClassLoader honors the project's classes first), but it is hostile to platforms that translate bytecode -- parparvm and Android both have to deal with two definitions of the same class living in different jars and can produce ambiguous output. Shadowing a framework class with a per-project class is exactly what the stub mechanism in the builders is meant to avoid: the generated class belongs in the per-build stub area, not in the framework jar. Changes: * Delete `CodenameOne/src/com/codename1/router/generated/` so the cn1-core jar no longer carries a Routes class. * `Display.init()` resolves `Routes.bootstrap()` via reflection and silently no-ops on `ClassNotFoundException`. A project without any `@Route` produces no Routes class -- `Display` just doesn't install the dispatcher. * `RouteAnnotationProcessor.finish()` no longer references "the framework stub" when there are no project routes -- there is no stub to leave alone. * Developer guide updated to call out why the dispatcher is per-project. The Maven plugin's `process-annotations` Mojo continues to be the place that writes the generated dispatcher into the project's `target/classes` at an early build step; the server-side builders receive the project bundle with that class already in it (or no class at all when the app has no `@Route`). No builder changes are required.

CLDC11's Class.java exposes forName and newInstance but not getMethod, so the previous `Class.forName(...).getMethod("bootstrap").invoke(null)` form did not compile against that bootclasspath. Switch to a self-registering constructor: the generated Routes class now declares a public no-arg ctor that calls Navigation.setDispatcher(this), and Display#init() does Class.forName(...).newInstance() to trigger it. Both calls are in CLDC11. Test updated to introspect rather than the removed static bootstrap method.

The correct injection point is the application stub each builder writes per build: it's compiled against the project's classpath, so a direct symbol reference is preserved by the same keep-rules that cover the rest of the stub. * Display.init no longer touches Routes. * RouteAnnotationProcessor.emitStubs now unconditionally writes a no-op Routes.java to target/generated-sources/cn1-annotations during the generate-sources phase. process-classes still overwrites it with the real dispatcher when @Route declarations are present. Projects with zero @Route still compile and run -- the no-op constructor simply doesn't install a dispatcher. * iOS builder (server-side BuildDaemon and the in-repo maven plugin's IPhoneBuilder) emit `new com.codename1.router.generated.Routes();` immediately before `Display.init(stub)` in the generated Stub.java. * Android builders (server-side BuildDaemon AndroidBuilder / AndroidGradleBuilder and the in-repo plugin's AndroidGradleBuilder) emit the same call in front of the first Display init in onResume. The reinit branches don't repeat the binding because the dispatcher is held statically by Navigation and survives a Display reinit. * Desktop production stub (cn1app-archetype template + the existing hellocodenameone example) binds Routes immediately before Display init too. * Developer guide explains the per-build injection model. Note: the simulator path (`mvn cn1:run`) currently does not auto-bind because the simulator's launcher is the cn1-core JavaSE port's Executor, which has no compile-time reference to a per-project class. `cn1:run-desktop` (which goes through the user's *Stub) does bind correctly.

The archetype-generated common/pom.xml now declares the generate-annotation-stubs and process-annotations executions, so every freshly archetyped project has a com.codename1.router.generated .Routes class on its classpath -- the per-platform stub's direct symbol reference resolves. Same update applied to the existing hellocodenameone sample. 2. The JavaSE simulator (Ports/JavaSE) now installs the dispatcher via Class.forName + newInstance in Executor#runApp just before Display.init. The simulator is the legitimate place for dynamic loading -- it runs unobfuscated, already spins its own ClassPathLoader, and Executor is already heavily reflective for loading the user's main class. For ParparVM iOS and Android the per-build application stub continues to bind by direct symbol reference; obfuscation rewrites both call site and target class together. 3. Vale flagged a 'do not' contraction in the routing doc; switched to 'don't'.

The generated stub then references com.codename1.router.generated.Routes but the javac classpath used to compile the stub doesn't necessarily include the framework jar, so compilation fails with "package com.codename1.router.generated does not exist".

Package-info.java files keep package-level docs above the package statement as they always have. * Stop hardcoding `new com.codename1.router.generated.Routes()` in application source. The archetype-generated `*Stub.java` template and the existing hellocodenameone sample stub no longer reference Routes; the JavaSE port instead installs the dispatcher in its `postInit()` override via `Class.forName(...).newInstance()`, which covers both the simulator-driven entry (Executor) and the desktop-production entry (per-app stub) without a static dependency in user code. Removed the now-redundant Class.forName from the JavaSE Executor. * Remove the orphan "Note: the per-project route dispatcher..." comment from Display.init -- it didn't annotate any code after the Class.forName itself was removed. * RouteAnnotationProcessor no longer emits a no-op Routes stub at generate-sources. Routes class now exists only when the project actually has `@Route` declarations, so the per-platform application stub's `zipHasRoutes(sourceZip)` check correctly skips the install line when there's nothing to install. * Wire the annotation Mojo into scripts/initializr's common/pom.xml the same way as the archetype, so projects bootstrapped from that sample also pick up routing out of the box. (The user shouldn't have to configure the Mojo themselves.) * Developer guide trimmed: dropped the "Wire the build" section (auto-configured by the archetype/initializr templates), replaced the "Enable Associated Domains in Xcode" prose with the existing `ios.associatedDomains` build hint (the iOS builder already writes the entitlement), and replaced the verbose `` example with a reference to the existing `android.xintent_filter` build hint. Both build hints already appear in the build hints table. Added a brief "How it works" section explaining the build-time scan + per-platform-stub binding in broader terms.

Revert the matching `scripts/initializr/common/pom.xml` edit entirely: that project is pinned to the released `7.0.244` plugin to demonstrate "users on the released version" and the new process-annotations goal doesn't exist there yet (the Hugo website build runs `mvnw package` against it and was failing with MojoNotFoundException). The initializr resource templates (barebones-pom.xml, kotlin-pom.xml, ...) likewise stay on the released goal set; they can pick up `process-annotations` when the next CN1 release ships with the new Mojo.
