    • Priority: Minor
    • Resolution: Cannot Reproduce
    • Component/s: core

      None
    • Environment:
      Jenkins 1.516, Redhat 5.6 64Bit, Tomcat 6,
    • Similar Issues:

      Description

      To reproduce:
      1. Install Jenkins 1.516 which comes with bundled CVS Plugin 2.8
      2. create a maven job using a CVS SCM and save it
      3. downgrade CVS plugin to 1.6
      4. restart jenkins

      Result: the job neither isnt't available in the "all" view, nor cant it be displayed by opening a bookmark with the job URL

      Expected: job is displayed at least in "all" view and can be called directly by using the job name URL, at least with an error message about non-supported plugin-data in the job

      Workaround: remove the <scm> section from config.xml and restart Jenkinks and configure CVS with the previous values

      In the log there a are lot of plugin-releated error messages:

          danielbeck Daniel Beck added a comment -

          Downgrading plugins (across major versions even!) is not a supported use case.

          That being said, newer Jenkins versions massively improved robustness when deserializing jobs (JENKINS-21024, JENKINS-22398). Therefore I'm closing this as Cannot Reproduce. Feel free to reopen if you can show this still occurs in 1.558+.

          Thanks, its fine for me.
          We are currently using a sticky revision of CVS 1.6 Plugin (because of JENKINS-18539) so it shouldn't happen on our installation again.
