I'm having difficulty setting up the dev workspace for Forge using IntelliJ, and would appreciate some help. While following CPW's tutorial (youtube.com/watch?v=G2aPT36kf60) on setting up the workspace, I've encountered a couple of errors. First, there is an unindexed Maven repository at files.minecraftforge.net/maven. Others have experienced this issue, however the solutions to those do not seem to be working for me. After running setupDecompWorkspace and the genIntellijRuns, then refreshing the gradle build by clicking the pair of blue arrows (which takes a very long time to finish), trying to run the "Minecraft Client" results in the attached screen.

 

 

Any help would be great.

That just looks like you didn't run setupDecompWorkspace or didn't refresh the gradle project. Did those two steps complete without error?

As for the unindexed maven repo: Ignore it.

Thanks for the pointer- I ran setupDecompWorkspace twice (the first time it had errors, the second time it completed successfully) and then was able to refresh gradle, run genIntellijRuns, and finally run the "Minecraft Client" process. Unfortunately, this now crashes with a nullpointerexception. Attached is the log file (same crash happens when run again).

What graphics card are you using? Make sure your drivers are up to date.

This is literally the one time in ten years that "updating graphics drivers" advice worked for me! Thanks for all your help, the game booted!
