error in opening zip file ForgeGradle

When I was trying to setup the dev workspace for Gradle, using eclipse. I've tried just about everything, including both methods in this thread http://www.minecraftforge.net/forum/index.php/topic,14048.0.html

Neither works, in the eclipse method, it can't find any projects. When I do the command line I get this error

bash gradlew setupDecompWorkspace

Any idea what I'm doing wrong?

Kill your .gradle folder in your home directory and try having ti download again, seems your internet derped and corrupted something.

Else you can install gradle manually.

Sorry to be stupid, but where is my home gradle folder? I tried deleting the "gradle" folder in the forge folder, but that didn't work.

Is there a tutorial on installing gradle manually?

Thanks, was thinking the forge  home directory. That worked, setting it up now.
