Discontinued

This project has been discontinued. I recommend using BON2 to deobfuscate mods and a regular Java decompiler to decompile them.

Minecraft Mod Decompiler

Decompiles and deobfuscates all Minecraft Forge mods in a specified directory and outputs the source files to another directory.

Please respect the individual mod licenses when using this tool.

Supported Platforms

This tool uses JD-Core-java for decompilation.

JD itself supports:

Linux 32/64-bit
Windows 32/64-bit
Mac OSX 32/64-bit on x86 hardware

Build

Clone the repository and run gradlew build. This will generate two JAR files in the build/libs directory:

MinecraftModDecompiler-<version>.jar, which contains only this tool
MinecraftModDecompiler-<version>-withdeps.jar, which contains this tool and all of its dependencies

The idea and eclipse Gradle plugins are included in the build script, so you can run gradlew idea or gradlew eclipse to generate an IDE project.

Usage

java -jar MinecraftModDecompiler.jar [options]
  Options:
  * -mappingsDirectory
       The directory containing the MCP mapping files (fields.csv and methods.csv)
  * -modDirectory
       The directory containing the mods to decompile
  * -outputDirectory
       The directory to output the decompiled classes to

For convenience, the included MCModDecompiler batch/shell scripts can be run with the same arguments after building in a cloned repository.

The MCP mapping files can be found in the MCP releases under the conf directory. If you've set up a ForgeGrqadle workspace, you can also find the mapping files in your Gradle cache (~/.gradle/caches/minecraft/net/minecraftforge/forge/<forge_version>/unpacked/conf for Minecraft 1.7.2 and later).
