We are using Multibranch Pipeline job on Jenkins. Sometimes during the scan, we receive an exception:

java.io.IOException: Unable to delete '/var/lib/jenkins/jobs/sample.job.build/branches/feature-P.of17kqq8ojl6.-PFT-repo'.

It causes that our scan fails so no new builds are created. Maybe this kind of error is not such a big problem so scan can proceed?
