[JIRA] [core] (JENKINS-25737) 'Run Parameter' build parameter is null when SCM/pre-SCM phase is started on remote-node.

Mon, 24 Nov 2014 06:47:21 -0800

Daniel,

(Using Jenkins 1.565.3, and Perforce SCM plug-in 1.3.29)

  1. Start Jenkins (I ran hpi:run)
  2. Add a dump remote node
  3. Configure a job to use as a 'Run Parameter' reference.
  4. Configure another job to use as a primry repro job
    • Add a run paramter and point it to the job created in step #3
    • Add an execution of the Perforce SCM plug-in.
      • You can use 'guest' as your use and workshop.perforce.com:1666 as your server
  5. Run job #3 to get at least one entry in the drop down

The job will fail with an obscure error that looks to be an issue with Perforce but while debugging the code, I noticed that it was because the 'Run Parameter' variable was NULL when the Perforce SCM plug-in was trying to use it to do substitution. The eactt error that I'm seeing is:

I've attached an example (jenkins-25747-example.tar) of the two jobs that I used to reproduce the error. It contains the two jobs that should be able to reproduce the error for you.
