  • First, get a release of RetroMCP from releases.
  • Run RetroMCP by double clicking on the JAR file or by launching it in terminal with java -jar
    If launched by the former method, a GUI should automatically show up. For the latter method, a console-based interface will show up.
  • Run the setup task
    • If you are using the console interface, select the desired version using setup command
      If no arguments are provided, RetroMCP will show the list of available versions, but you can also specify one of existing versions to skip it.
    • If you are using the GUI, select the desired version in the top right corner
  • After that, you're ready to decompile Minecraft.
    • In console, run the decompile command
    • In the GUI, click the button that says "Decompile" in the top left corner
  • It's done. You can open workspace in eclipse or workspace/Client/Client.iml and workspace/Server/Server.iml if you're using IntelliJ.

In RetroMCP-Java versions post release v1.0, workspaces are not created automatically. This is done for portability reasons. The minecraft_client and minecraft_server folders can be imported as projects into an existing workspace. You can also create a workspace folder for Eclipse and import them that way.
