Gooey Iron is a MultiMC/packwiz GUI-based pack testing tool.

It runs MultiMC and loads a packwiz modpack into it, and exits with 0 if Minecraft runs, 1 if Minecraft fails to run.

Intended to be used in conjunction with Jenkins to check if a modpack will crash when loaded into MultiMC and ran.

Example: Your modpack resides in ../rivers-of-iron-mc/.

pipenv run python ./gooeyiron.py -f ../rivers-of-iron-mc/ -t multimcgui

• Use AWS/Jenkins VM/Bare metal Jenkins and poll main branch to see if modpack would work

• VM with VBox Guest Additions and DirectX support for OpenGL...

  • No OpenGL. This means no main menu. But, forge loading screen shows.
  • I can ditch the check for main menu IF it's detected that a VM is being used...
  • Then look for a black screen,
  • Then look for the string Forge Mod Loader has successfully loaded (...) mods in C:\tools\MultiMC\instances\<NAME>\minecraft\logs\latest.txt
  • Then loading is done for non-GPU instances.
  • Also, save the log in Jenkins.

• AWS pricing for GPU is garbage, cheaper to buy another PC

• Azure pricing for GPU is garbage, cheaper to buy another PC

• You don't need a GPU. Minecraft will start black. The script takes this into account.
• 2 Processors
• 5120MB RAM
• 256MB of VRAM
• No 3D Acceleration
• VBoxSVGA Graphics Controller
• Give Minecraft ~4GB RAM
• You must log into MultiMC.
• Disable VBox Guest Addition mouse integrations.
• SET PIPENV_SKIP_LOCK env var to True

That's right. You need to turn a Windows User who's logged on into a slave that Jenkins uses to build.

Tag the build and the slave too:

Download slave agent JNLP from (URL may be different):

http://localhost:8080/computer/gui%20slave/slave-agent.jnlp

netplwiz

• Download JNLP file
• Open Task Scheduler
• Make task with command slave-agent.jnlp
• Set task to run on login
• Restart and test

• May have to forward port under network adapters if you want to visit Jenkins Web UI from host machine.
