The pitpublisher in pipeline throws an exception when no reports are found. This is not consistent to other publisher plugins which only write a warning to the log files.

This should be changed to emit a warning to log instead of throwing an exception.

My code:

   step([$class              : 'PitPublisher',
                  mutationStatsFile   : '**/target/pit-reports/mutations.xml',
                  killRatioMustImprove: false])
