I had exactly the same problem! But i fixed it. How? First of all, this: is NOT a proper answer because it literally says "I don't want to spend my time helping you. F**k off". This spurns most of the potential devs and discourages them. The official documentation is neither very helpful for newcomers. I can't say that it is a piece of shit because it is almost non-existent, so you can't scientifically prove that it is shit if you can't measure its 'shitness'. SO, the actual answer starts here. Mods using mixins have mappings for OBFUSCATED minecraft only, so these mods will inevitably crash in deobfuscated environments such as development environment. So, to fix this you need to use some mechanism to automagically® remap existing maps. Applying org.spongepowered.mixin will do. Put this into build.gradle: buildscript { repositories { mavenLocal() jcenter() maven { url = "https://maven.minecraftforge.net/" } maven { url = "https://repo.spongepowered.org/maven" } } dependencies { classpath 'net.minecraftforge.gradle:ForgeGradle:5.1.+' classpath 'org.spongepowered:mixingradle:0.7-SNAPSHOT' } } apply plugin: "org.spongepowered.mixin" This is a very bad piece of code. I know I should've done this in another way. But I don't know the right way because I'm noob at modding.
