It looks like the Jira and Jenkins integration has come a long way since when I've last looked at it. The one major downside I can see is that the Jira development panel doesn't seem accessible via API, so there aren't plugins that can update the development panel with Jenkins build information and status. The same goes for information from SCM tools other than bitbucket.
Has anybody figured out a way to do this? Ideally, I can (with some scripting or a plugin) update the development panel with build info and status from Jenkins, and with SCM info from perforce/svn.
