ForgeWrapper

Allow MultiMC to launch Minecraft 1.13+ with Forge.

ForgeWrapper has been adopted by MultiMC, you do not need to perform the following steps manually. (2020-03-29)

For other launchers

  1. ForgeWrapper provides some java properties since 1.4.2:

    • forgewrapper.librariesDir : a path to libraries folder (e.g. -Dforgewrapper.librariesDir=/home/xxx/.minecraft/libraries)
    • forgewrapper.installer : a path to forge installer (e.g. -Dforgewrapper.installer=/home/xxx/forge-1.14.4-28.2.0-installer.jar)
    • forgewrapper.minecraft : a path to the vanilla minecraft jar (e.g. -Dforgewrapper.minecraft=/home/xxx/.minecraft/versions/1.14.4/1.14.4.jar)
  2. ForgeWrapper also provides an interface IFileDetector, you can implement it and custom your own detecting rules. To load it, you should make another jar which contains META-INF/services/io.github.zekerzhayard.forgewrapper.installer.detector.IFileDetector within the full implementation class name and add the jar to class path.

How to use (Outdated)

  1. Download Forge installer for Minecraft 1.13+ here.
  2. Download ForgeWrapper jar file at the release page.
  3. Since ForgeWrapper 1.5.1, it no longer includes the json converter, so you need to build it by yourself:
    • Download ForgeWrapper sources.
    • Extract the zip and open terminal in the extracted folder.
    • Run ./gradlew converter:build command in terminal and get the jar from ./converter/build/libs
  4. Run the below command in terminal:

    java -jar <ForgeWrapper.jar> --installer=<forge-installer.jar> [--instance=<instance-path>]
    

    Notice: If you don't specify a MultiMC instance path, ForgeWrapper will create the instance folder in current working space.

  5. If the instance folder which just created is not in MultiMC/instances folder, you just need to move to the MultiMC/instances folder.

  6. Run MultiMC, and you will see a new instance named forge-<mcVersion>-<forgeVersion>.
