About reporting crash

I recommend installing MoreCrashInfo mod. This mod will print more useful information to crash reports, and these can help us locate errors faster.

For Development Environment

1. There is a project called OptiFineDevTweaker can help us use OptiFine under development environment. You should put OptiFine itself and OptiFineDevTweaker mod to <projectDir>/run/mods folder.
2. If your project doesn't depend on Mixin, you should put MixinBootstrap mod to mods folder.
3. You should also put OptiForge jar with -deobf suffix to mods folder.

Notice:
1. If you redefined your Gradle user home, you should add a VM argument:
-Dofdev.mcjar=<gradle.user.home>\caches\forge_gradle\minecraft_repo\versions\1.15.2\client.jar
2. OptiFineDevTweaker will dump all deobfuscated OptiFine classes to ./run/.optifineDev.classes folder.
3. There are some useful Mixin properties for debugging: Mixin Java System Properties
I recommend you add -Dmixin.debug.export=true, it can dump all mixed classes to ./run/.mixin.out/class folder.
4. The recommended mcp mappings version is snapshot_20200612-1.15.1
