I need help, every time I try to build my mod, using the gradlew build, it gets most of the way done, and stops at retromapReplacedMain. I let it set for about an hour, and nothing happened. I don't think it's a problem with my mod being too big, as I have only added in a few blocks as of yet. Below is what the command prompt output is.

Can anyone help at all? This is really annoying, I don't know what causes it.

I'm having the exact same issue  :'( any help would be greatly appreciated.

Thank God I found this after hours of research: https://www.bountysource.com/issues/36280497-remapping-source-fails-for-some-classes

 

Hope it works for you too man
