hum, I'm now seeing another exception:
Cause: Timeout waiting to lock cache directory
/work/users/jrobicha/ds2/DS2.trunk/build/.gradle/1.0-milestone-5/taskArtifacts.
It is currently in use by another Gradle instance
I've attached the full stack trace.
This exception occurs, again, when I'm launching 2 tasks at the same time.
Any workaround? i didn't had this issue. Should I delete the .gradle
directory ? Is that what is meant by doing "gradle clean"?
Jp
