multi-scm plugin causes NPE to console log when configuring multi-branch pipeline job

XMLWordPrintable

      The multiple-scms plugin causes a null pointer exception in the console log when configuring a multi-branch pipeline job.

      If I remove the multiple-scms plugin, no NPE is reported.

      The multiple-scms plugin is not used in the job definition, (nor anywhere in my environment), so I removed it from my installation. When I remove it, the null pointer exception no longer appears.

      This bug is logged in case others encounter a similar stack trace.

      The stack trace is:

          WARNING: Caught exception evaluating: h.filterDescriptors(it,attrs.descriptors) in /job/Git-Client-Folder/job/git-client-pipeline-github/configure. Reason: java.lang.NullPoint

      Steps to duplicate the bug:

      1. Clone my docker repository and checkout this branch 
            $ git lfs clone https://github.com/MarkEWaite/docker-lfs JENKINS-45085
    $ cd JENKINS-45085
    $ git lfs fetch origin origin/explore-JENKINS-45085
    $ git checkout -b JENKINS-45085 JENKINS-45085
      2. Build and run the docker image 
            $ docker build -t jenkins:JENKINS-45085 .
    $ docker run -i --rm --publish 8080:8080 jenkins:JENKINS-45085
      3. Open the Jenkins URL (http://localhost:8080), open "Git Client Plugin Folder" and "Git Client Branches - Jenkinsfile (GitHub)"
      4. Click the "Configure" link while watching the console log - null pointer exception will be reported to console (but not to the user interface)

      Steps to show that removing multiple-scms resolves the problem:

      1. Checkout branch without multiple-scms 
            $ git lfs clone https://github.com/MarkEWaite/docker-lfs JENKINS-45085-avoided
    $ cd JENKINS-45085-avoided
    $ git lfs fetch origin origin/explore-JENKINS-45085

    $ docker run -i --rm --publish 8080:8080 jenkins:JENKINS-45085-avoided
      3. Open the Jenkins URL (http://localhost:8080), open "Git Client Plugin Folder" and "Git Client Branches - Jenkinsfile (GitHub)"
      4. Click the "Configure" link while watching the console log - null pointer exception will not be reported

          Description Original: The multiple-scms plugin causes a null pointer exception in the console log when configuring a multi-branch pipeline job.

          If I remove the multiple-scms plugin, no NPE is reported.

          The multiple-scms plugin is not used in the job definition, (nor anywhere in my environment), so I removed it from my installation. When I remove it, the null pointer exception no longer appears.
