We're using Hudson continuous integration server frequently on projects. But Hudson seems lacking of proper versioning of the jobs configuration.
A few times, this has lead to problems: Somebody changes or tweaks the configuration on jobs and something that used to work stopped working.
I have tried to version-control jobs on my local Hudson server (on my laptop). But this is not optimal: 1) it's only for me. 2) i need to mirror jobs from a central build server – and may also need to modify them to work locally. 3) It's pretty cumbersome to setup .gitignores for files to ignore.
As far as I know, there is no way in Hudson to view change history of jobs, and no plugin does it either.
Also, there seems to be no way to export/import settings.
So the question is: How do you keep track of changes? Both in jobs and in general setup of Hudson?
