PaperMixin

Mixin for Paper-based Minecraft servers!

This is not magic, and you'll need JetBrains Runtime to properly run it.

How to use

1. Download https://github.com/JetBrains/JetBrainsRuntime and extract it somewhere (If you are using itzg/minecraft-server, you can mount it as a volume on /opt/java/openjdk)
2. Add -XX:+AllowEnhancedClassRedefinition to your JVM arguments
3. Build the project and add the resulting jar at build/libs/PaperMixin-x.x.x.jar to your server's plugins folder
4. Create mixin module as per example directory
5. Add the resulting jar of the mixin module to <server root>/modules folder

A lot of hacks are used to make this work, so if it doesn't work, please report it, and I'll try to fix it.

Why JetBrains Runtime?

Other Java Runtime environments do not allow adding or removing methods. However, JetBrains Runtime allows it.
