Mixin: A Powerful Bytecode Weaving Framework for Java

Mixin is a trait/mixin and bytecode weaving framework for Java using ASM, hooking into the runtime classloading process via pluggable services. It supports Mojang's LegacyLauncher (deprecated in favor of the more extensible ModLauncher), and is compatible with Java 8 and later. Mixin offers extensive documentation, Maven repositories, and tooling, including an Annotation Processor for handling obfuscation tasks, and integration with Eclipse and IntelliJ IDEA. Its version history details feature additions and bug fixes, aiding developers in choosing the appropriate version.
