Hi Manuel, What do you see in the console when you execute: $ java -version
To get back to 1.6 you will have to put it before 1.7 in PATH environment variable. Can you check how is it set up now? Can you also check $JAVA_HOME? You should also try running your Ant script outside of Jenkins. Andrey On Jun 19, 2012, at 5:38 AM, Manuel Dahmen <manuel.dah...@gmail.com> wrote: > What's this?
