[JENKINS-16421] gerrit-trigger UI elements 404 on jenkins 1.499

It appears as if the jenkins plugin is somehow unable to register its URLS with jenkins correct. Clicking the link to retrigger a build or select builds to retrigger takes me to /jenkins/gerrit_manual_trigger, which is 404. Also, the retrigger icon, trying to load from /jenkins/plugin/gerrit-trigger/images/icon_retrigger24.png is also 404. The trigger does appear to work when configured from a job.

I tried rebuilding the latest code from github and changing the jenkins-ci dependency to 1.480. By forcing the build to skip tests, I got it to compile but after installation the behavior is the same. Prior to upgrade to 2.7.0 + Jenkins 1.499 I had everything running with the same config with gerrit-trigger 2.5.2 and Jenkins 1.4.463. I'm not seeing anything gerrit-trigger related in the logs.

I'm happy to help troubleshoot however I can, but I'm a bit at a loss where to start currently. Any ideas?

Thanks!

• environment: RHEL5, Sun Java 1.6.33, Jenkins 1.499

Start by reproducing the missing /jenkins/gerrit_manual_trigger page and /jenkins/plugin/gerrit-trigger/images/icon_retrigger24.png on Jenkins 1.499, then trace how the gerrit-trigger plugin registers these URLs and resources. Done means the retrigger links and icon load successfully while configured job triggers continue to work.
