I did that. I have permission to do everything in that folder. It can download and unzip http://services.gradle.org/distributions/gradle-1.8-bin.zip to there, so that shouldn't be the problem. Yes I tried that, but it's still not working. I also checked, that directory (or anything inside it) is not being used by another application.

It took me a while to setup gradle so it build my mod. After getting it to work, I wanted to run the script on my Jenkins, which didn't work. After googeling about an hour, I decided to ask for help here. That's the StackTrace: FAILURE: Build failed with an exception. * What went wrong: A problem occurred configuring root project 'SOMETHING'. > Could not open buildscript class cache for build file

Thank you in advance for your help. - Aroma1997

I don't think, it's FernFlower, because the FF jar comes with MCP and on one on one of the jenkins, it worked. Why should the jar be corrupted on one, but not on the other?

For me, that's not the problem. On one of my Jenkins servers, it works, on the other, i get that problem. I'm using the same ANT build script for both.

Same problem here. Only difference, I'm running on linux. I tried with python 2.7, python 2.6 and python 3.3. None of them worked! :-(
