THIS IS NOT A FORK!

This mod can:

  • Download and install Cleanroom automatically if you are running MMC-based launchers
  • Download and launch Cleanroom if you are using other launchers

Difference compare to official one:

  • A config option to use local Cleanroom mmc pack, which allow the installation of action builds
  • Proxy config of pack & libraries downloading
  • Custom library path
  • No version picker - always use latest release if no local pack given

About Java 8u51: Official launcher ships with outdated Java 8u51 (released 2015), which doesn't contain certificates of later Let's Encrypt (used by Cleanroom maven) and Azure (used by libraries.minecraft.net).

The mod will add those certs into JVM if old java detected. They are either get directly from root certificate's website or convert by using openssl.

If you want to:

  • Update Cleanroom version: remove mmcpack.zip and mmcpack/ folder in relauncher/, then launch the game.
  • Rollback to Forge: Disable the mod if you are using regular launcher, change game version, lwjgl version and Forge version back to regular in MMC instance setting if you are using that.

By MMC-based launchers, I mean MultiMC, PolyMC and PrismLauncher.

You need to install a Java 21 to use this!

This is a client only mod! For server, please download installer jar from Cleanroom repository.

If anything gone wrong, remove cleanroom_relauncher.cfg config file and try again!
