When starting Xcfb fails the build goes to ABORTED but it should FAIL
rationale: We have many builds, probably because of an upgrade of jenkins/xvfb plugin our build was missing configuration so it went into ABORTED all the time. It took us quite a while to see that, if it would have failed instead we would have seen this issue directly.
Building in workspace /var/lib/jenkins/jobs/test/workspace
ERROR: No Xvfb installations defined, please define one in the configuration. Once defined you’ll need to choose one under Advanced options for Xvfb plugin job settings and save job configuration.
Build was aborted
