This has been scratching my head, I've started from scratch about 5 times now with slightly different set up each time, but every time it gets to mergeJars it fails and doesn't tell me much more. Looking at other people's logs it seems like it's actually supposed to skip, but no idea how to make it do that.

 

 

log file: https://gist.github.com/anonymous/d93ae9c91b616ca2ef3c

 

Setup:

 

Windows 7 home 64x

Jdk and Java both: 7 update 55

Path set to C:\Program Files\Java\jdk1.7.0_55\bin

JAVA_HOME set to C:\Program Files\Java\jdk1.7.0_55

Forge version: forge-1.7.2-10.12.1.1084-src (Latest as of 5/20/14)

Directory I extracted zip to: C:\development\forge

 

Reproduce error:

 

extract forge to directory

shift+right click > run command window

type gradlew.bat setupDecompWorkspace

Log file above is produced(It's run before, which is why it only took 28 seconds as opposed to 10 minutes) but always stuck on that.

 

EDIT: Either redownloading eclipse or redownloading forge fixed it. I dunno. Follow Wuppy's tut from scratch if you have this problem.

 

Protip: read the log it tells you how to get more information.

But looks like something in your install got corrupt running a cleanCache to rebuild everything would probably solve it.
