We've had the release plugin working on our Jenkins installation for quite a while and used the lastSuccessfulReleaseBuild permalink as a way to publish our downloads. A couple weeks ago this just stopped working. I'm not sure if it was the upgrade to v2.10 or not, although that happened in close proximity time-wise to when the problem started occurring.

When I started looking into it, I realized that nothing from the release plugin was working: we don't have the lastSuccessfulReleaseBuild permalink, the Release option is no longer available in pop-ups, and previous release builds are no longer marked as release builds (although they are still marked as "keep forever"). I included a screen shot of one of our projects where you can see the lack of lastSuccessfulReleaseBuild permalink as well as a build marked "keep forever" that was our previous 1.7.4.1 release.

I've tried removing the release plugin and reinstalling it with no change. I've removed it, completely deleted it from the plugins folder (release.jpi, release.hpi.pinned and the release folder), and reinstalled it. No change. There are no errors relating to the release plugin in the jenkins.log that I can see.

Here are all of the files for the plugin (as far as I know) in the plugins folder:

Here's everything from jenkins.log from the first mention of release to the last:

I restarted the server after the installation but no change.

Please let me know if I can provide any other info to get this problem sorted out.
