      Description

      After upgrading to jenkins-1.652-1.1.noarch, I get a ServletException error whenever I try to configure a job. This happens in both firefox and safari. When I downgrade jenkins to 1.651, this issue disappears.

      I've attached the Jenkins log, which seems to indicate that Gradle can't be found:

      WARNING: Caught exception evaluating: d.helpFile in /job/HFCS_Tools_SLOC/configure. Reason: java.lang.reflect.InvocationTargetException
      ...
      Caused by: java.lang.NoClassDefFoundError: hudson/plugins/gradle/Gradle
      ...
      

      The stack trace on the "Configure" error page (Screen Shot 2016-03-07 at 11.54.44 AM.png) mentions the ScmSyncConfigruationFilter and ScmSyncConfigurationDataProvider classes, so I figured this was an issue with the Scm-Sync-Configuration-Plugin.

            Daniel Beck suggests that the fix of JENKINS-25440 might have caused this. Is there a straightforward way to reproduce this from scratch? Messages in your log file during startup?

            Nothing to do with the SCM Sync plugin. TBD whether a core bug, or something wrong with the Gradle plugin, or a configuration problem in your installation.

            I ran a Jenkins dev build, installed the Gradle plugin, created a freestyle project, added a Gradle build step, saved, reconfigured. No exception.

            I searched through /var/lib/jenkins for Gradle/gradle, and it looked like the only place gradle was mentioned in the file name was the artifactory plugin. So I disabled the Artifactory Plugin, restarted Jenkins (1.652), and then went to a job's configure page, and the issue went away (there were a few permission errors related to the artifactory plugin no longer existing on startup).
            I then dug into this a little more, and it turns out that the Gradle (1.24) plugin was never installed on my Jenkins machine. I installed it, re-enabled the artifactory plugin, and then went to a Job's configure page... and everything worked.
            I've also posted this issue on the JFrog Artifactory Plugin JIRA at: https://www.jfrog.com/jira/browse/HAP-699
            Jesse Glick Thanks for your help!
            Sven Finsterwalder Is the Gradle plugin installed on your Jenkins instance?

            Possibly: I only noticed the issue when I was upgrading Jenkins, so I'm not 100% sure if it is a duplicate or if something else triggered the issue.
