I'm glad to announce my alternative OS X installer for Jenkins is now compatible with OS X 10.8 Lion.
But why another Jenkins installer for OS X? Two reasons: 1) Jenkins.app predates the official Jenkins installer by a few months. (First commit was on 2011-02-08 using the Fossil SCM.) I have always used Jenkins.app myself at home. I have not made much noise about it because I believed everyone was happy with the official installer. 2) Lately I have become aware that some people have trouble with Jenkins on Mac. If you use the official Jenkins Mac OS X installer which sets up Jenkins as a background daemon, you might have problems with automating code signing or running a Mac application that needs access to the GUI session to display windows. These problems are caused by Jenkins running as a dedicated user and as a launch daemon (= a background service) with no access to another user's keychain or GUI session. Launch daemons are designed to handle specific system level maintenance tasks and they are cut off from anything a user might want to do, like display a window or move the mouse. Jenkins.app is an alternative way to run Jenkins on the Mac. Jenkins.app runs Jenkins as the user who launched it, right there in the user's GUI session context. Jenkins.app has no windows, only a Dock icon and a menu to quit Jenkins. It is easy to to play with Jenkins, starting and stopping it at will. Earlier versions of Jenkins.app did not work on Lion but I only found out after I did a clean re-install of my Mac. (Hey Apple, thanks!)
