      Description

      I hit a null pointer exception trying to override the default version of the Shared Groovy LIbraries plugin in a multibranch pipeline job. Please see the shared-libraries-global-config.png and shared-libraries-job-config.png for the setup.

      When setting up the job config to override the global default value, (in my case a branch), it correctly picked up the commit hash of the head of the branch. Only after running the job do I get the null pointer exception.

      Here is the stack trace that displays in the job config when I click the ERROR link:

          phiche Philip Cheong added a comment -

          The error was caused by not specifying the Source Code Management section in the job of course.

          The plugin should perhaps handle the exception a little better as shown in correct-shared-libraries-job-config.png which is what is displayed after removing the Source Code Management section and refreshing the page to validate it.
