I can't get it to build either on the command line with gradle directly or in IntelliJ.. well, it builds but because it won't obfuscate this one mixin it won't boot the game with the mod installed.

When running despite this it does this:

[18:05:02] [main/FATAL]: Mixin apply failed locks.mixins.json:WorldMixin -> net.minecraft.world.level.Level: org.spongepowered.asm.mixin.injection.throwables.InvalidInjectionException Critical injection failure: @Inject annotation on strongCheck could not find any targets matching 'setBlock(Lnet/minecraft/core/BlockPos;Lnet/minecraft/world/level/block/state/BlockState;II)Z' in net.minecraft.world.level.Level.

Locks are going to be slower to update lately, mainly because developers don't have much time and are planning to refactor locks

Yes, this is due to the fact that the refmap name is not set when using arch gradle, which will cause the file name to be different from the setting, and the file name needs to be changed manually

fix in this

It doesn't seem to fix it? Is the refmap file maybe not in the repo?

Yes, it is automatically generated after archloom builds the jar.

Well the exact same build error happens even with this fix..

Oh, this is a strange problem with archloom, rebuild in idea and then run the jar task, it disappears again, don't care
