Hi Jan, Thanks for your reply!
Based on your message, I started playing with the different ways of plugin updates and with the Jenkins installation itself. What I notices is the following: Before changing anything, [jenkins]\plugins\ contains a translation.jpi with time stamp 3/23/12 9:39 and a folder translation. I manually upload the 1.9 hpi of the "Translation Assistance Plugin". In the installation folder [jenkins]\plugins there is still a file translation.jpi but now with timestamp 3/23/12 11:34 This is somehow what I would expect since I uploaded the file (with *hpi extension though). I restart Jenkins and now, translation.jpi has the former timestamp again 3/23/12 9:39. So apparently, the update has no effect and simply was ignored. Next try: I shut down Jenkins, remove the [jenkins]\plugins\translation.jpi and the [jenkins]\plugins\translation folder. I restart Jenkins and the folders reappear. Where do they come from? Is it possible that Jenkins simply overrides anything which I upload/update while starting? I must do something fundamentally wrong... Regards, Paul
