All of the issues that were opened on the Hudson Jira for the Perforce plugin are still open, but I’m unassigning those that are assigned to me. I’ll continue maintaining the Perforce plugin against Jenkins, so bugs will be tracked there, and any fixes I make will be made in the Jenkins repository. Note that the Jenkins version will still work for Hudson until Oracle/Sonatype and/or the Jenkins Community decide to break cross-compatibility.
I’m not saying the Hudson version is dead, just that it doesn’t have an active maintainer. Someone may take over maintaining it, but as far as I know, only one person has been assigned to working on Hudson and the hundreds of plugins written for it.
