Ii followed the documentation for installing 4.0+ geckolib and could not resolve this issue; I'm getting a bunch of errors along the lines of

• Exception in thread "main" java.lang.module.ResolutionException: Modules org.jetbrains.annotations and geckolib export package org.intellij.lang.annotations to module xaeronbtslotids
• Exception in thread "main" java.lang.module.ResolutionException: Modules org.jetbrains.annotations and geckolib export package org.intellij.lang.annotations to module minecraft

The precise conflicitng modules change each time i run runClient, I suspect this has something to do with the mixins? They aren't something i've dealt with before

Here's links my gradle layout, i have a rootproject with 2 subprojects, my API and my main mod files. I have skipped linking the API since it doesnt touch geckolib

Root Project

build.gradle

gradle.properties

settings.gradle

Sub-Project Core

You shouldn't be using cursemaven for dev work for geckolib
Use the actual maven - follow the instructions on the wiki for setting up your dev space
