This is VERY weird. I've been using Eclipse for over 4 years, and for some reason my Subversion integration disappeared today. I've uninstalled and reinstalled Subclipse 3 times already and it never re-appears. My installation log and configuration shows subclipse installed, but all I have under 'Team' in preferences is 'CVS', no Subversion. What would make this happen?
After an upgrade to eclipse via update-manager on Ubuntu, my team provider plugins appeared again and are working perfectly. Very bizarre.
