We recently had an old Hudson-Jenkins install (running on Windows Server 2k8 R2) go bad (Jenkins service refusing to start - copying back war file did not resolve as it used to when this would happen) and were unable to resolve the issue.
This installation pre-dates anyone currently on this project and I have to admit I am clueless as to how it is setup and works, so troubleshooting has been difficult. I installed a fresh version of Jenkins (windows installer, latest) and moved over our jobs folder but am not able to get packages to build. Jenkins starts, it sees the previous jobs and their properties seem intact, and Jenkins can see our SVN repositories and seems to be able to read them. However, when we try to build it just doesn't see changes and doesn't output any builds.
I tried several means of 'upgrading' - installing new version fresh and moving over the jobs folder - installing new version on top of old version in its location, and various degrees of switching war files and other folders and files back on top of a new install. All yield the same result - Jenkins runs, sees the SVN repository, has the jobs info - but produces no builds.
Any suggestions? If you had a bad install (old version, probably 2+ years) and wanted to just install fresh and move the stuff over what all needs to move (jobs folder, obviously ... but what else)?
