GlowRemapper

GlowRemapper is a simple Gradle plugin to rename methods on classes in a compiled Java archive. Provided with a file containing a list of mappings and an input jar, GlowRemapper produces a jar where the mappings have been applied.

All classes which inherit from a class with remapped methods will also have their corresponding methods remapped.

A single task, remap, is added, explained below.

Usage example

mappings.txt:

test/ClassName oldMethodName (I)V newMethodName

build.gradle:

// add dependency
buildscript {
    repositories {
        maven { url "http://repo.glowstone.net/content/groups/public/" }
    }
    dependencies {
        classpath 'net.glowstone:remapper:1.0'
    }
}

// configure remapper
remap {
    mappingFile = file('mappings.txt')
    inputJar = file('build/libs/original.jar')
    outputJar = file('build/libs/remapped.jar')
}

All configuration options available:

• mappingFile: specifies the file to read mappings from.
• inputJar: specifies the input jar to process.
• inputTask: a task which produces an archive (e.g. jar, zip, or shadowJar) to use as input.
• outputJar: specifies where to write the remapped jar.
• outputFilename: specifies the filename of the remapped jar in the same directory as the input.

mappingFile and one of inputJar or inputTask are required. If no outputJar or outputFilename is specified, one is chosen automatically.
