After you pushed your changes to Gerrit, the Saros-Gerrit job will be scheduled on the Jenkins CI system but the build fails.
The execution of this job might fail and the most common errors are
- missing files
- build failures due building on an older OSGI/Eclipse version
- test failures because the tests are run without SWT/GUI being initialized
In case the build has failed it can be difficult to find the error in the ant log. The easiest is to search for ERROR in the console log of the job. An example for a build failure is Job 24, try to find the error.
