MixinGradle is a Gradle plugin which simplifies the build-time complexity of working with the SpongePowered Mixin framework for Java. It currently only supports usage with ForgeGradle.

Features

MixinGradle automates the following tasks:

• Locating (via ForgeGradle) and supplying input mapping files to the Mixin Annotation Processor
• Providing processing options to the Annotation Processor
• Contributing the generated reference map (refmap) to the corresponding sourceSet compile task outputs
• Contributing the generated SRG files to appropriate ForgeGradle reobf tasks

Using MixinGradle

To use MixinGradle you must be using ForgeGradle. To configure the plugin for your build:

1. Add a source repository and the MixinGradle dependency to your buildScript -> dependencies block:

buildscript {
       repositories {
           <add source repository here>
       }
       dependencies {
           ...
           classpath 'org.spongepowered:mixingradle:0.7-SNAPSHOT'
       }
}

Please ensure you are using the correct version of MixinGradle for your ForgeGradle version. Versions are not interchangeable.

ForgeGradle Version	Mixin Version	MixinGradle Version To Use
2.3	0.8 and below	0.6-SNAPSHOT
3.0+	0.8	0.7-SNAPSHOT

2. Apply the plugin:

apply plugin: 'org.spongepowered.mixin'

3. Create your mixin block, specify which sourceSets to process and provide refmap resource names for each one, the generated refmap will be added to the compiler task outputs automatically.

mixin {
       add sourceSets.main, "main.refmap.json"
       add sourceSets.another, "another.refmap.json"
}

4. Alternatively, you can simply specify the ext.refMap property directly on your sourceSet:

sourceSets {
       main {
           ext.refMap = "main.refmap.json"
       }
       another {
           ext.refMap = "another.refmap.json"
       }
}

5. You can define other mixin AP options in the mixin block, for example disableTargetValidator and disableTargetExport can be configured either by setting them as boolean properties:

mixin {
       disableTargetExport = true
       disableTargetValidator = true
}

or simply issuing them as directives:

mixin {
       disableTargetExport
       disableTargetValidator
}

You can also set the default obfuscation environment for generated refmaps, this is the obfuscation environment which will be contributed to the refmap's mappings node:

mixin {
       // Specify "notch" or "searge" here
       defaultObfuscationEnv notch
}

Building MixinGradle

MixinGradle can of course be built using Gradle. To perform a build simply execute:

gradlew build

To add the compiled jar to your local maven repository, run:

gradlew publishToMavenLocal
