FTB Launcher with Java 8 forced


UPDATE: This package is obsolete, get the upstream AUR version instead!

As of January 16, 2020, version 1.5.0 of FTB Launcher has been made available on the official AUR (feedthebeast). Shortly after that, the AUR package was updated to depend upon java-runtime=8 and the launch script was updated to use Java 8 binaries by default, making this version redundant. The commit that implemented this change is available here.

My old customized version of the package is outdated remains here (and it's documentation below) for archival purposes only, please grab the updated version from the AUR!

FTB Launcher

My version of the feedthebeast AUR package is a simple modification. It simply forces the use of OpenJDK 8's JRE as the default if it's installed, even if it's not the default. This is beneficial because FTB's authlib fails to load under Java 12, and Minecraft performs like shit on most non-8 JREs. Using this version you don't have to change your default JRE to 8 to get Minecraft working correctly as long as it's installed.


As an Arch user you probably have already heard this a million times, but to reiterate: DON'T USE AUR PACKAGES UNLESS YOU KNOW WHAT YOU'RE DOING AND YOU TRUST THE PACKAGE DISTRIBUTOR!

  1. Clone this repository

  2. cd into it

  3. Run makepkg -isrf

About the recommended makepkg arguments:

  • -i automatically builds and installs the package
  • -s uses pacman to fetch any required dependencies for building and installing
  • -r removes build dependencies after the build is completed (to keep your system nice and clean)
  • -f forces a rebuild in case it's already built

Bye. That's it. I have nothing else for you.
