      In the jenkins.log log file there are many exceptions. I will attach text files with examples. Some of the exceptions seem to point to the Gradle Plugin but I may be wrong about that. I can't easily uninstall the Gradle Plugin to test, because we depend on two plugins which have the Gradle Plugin as a dependency.

      For now a Jenkins downgrade to 2.142 solves the issue.
