Hello, this is how I embed the jar using my buildscript

buildscript {
    repositories {
        maven { url = 'https://files.minecraftforge.net/maven' }
        maven {
            url = "https://repo.spongepowered.org/maven"
        }
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath group: 'net.minecraftforge.gradle', name: 'ForgeGradle', version: '3.+', changing: true
        classpath 'org.spongepowered:mixingradle:0.6-SNAPSHOT'
    }
}

build.dependsOn signJar

    repositories {
        maven {
            url "file:///${project.projectDir}/mcmodsrepo"
        }

    }
}

The packaging seems fine, no errors are thrown and the files are successfully signed. But when I load it outside of the dev environment it crashes with this at the start suggesting that the library was not in fact extracted:

I have searched for the issue with dependency extraction but I was not successful. Any help would be appreciated

Thank you, can you recommend a work around for this or should I try to handle it myself?

Thank you, the only alternative to avoiding coremodding in my case is making a PR. That was planned for after the system I have in mind is stable and using mixins makes porting easier.

 

I'm guessing that in the correct order, a PR is made first?

Fair, I will begin working on the addition to forge then.

Edit: This will need far more changes to be convenient. I understand why nobody has added this as a feature of forge yet. Will try to find another way to mess with UseActions
