I'm trying to get this to work with IntelliJ, and after going through the initial setup (running the gradle tasks to decompile minecraft and setup project build settings), I keep getting this error:
Unindexed remote maven repositories found. [Disable...]
The following repositories used in your gradle projects were not indexed yet:
http://files.minecraftforge.net/maven
If you want to use dependency completion for these repositories artifacts,
Open Repositories List, select required repositories and press "Update" button
And if I try to do that, this error appears: http://i.imgur.com/pvag9vK.png
This is driving me bananas. What am I doing wrong?
