I've installed Subversive and want to switch to the Subclipse plugin.
After uninstalling Subversive via About Eclipse -> Installation Details -> Uninstall... and installing Subclipse, there are now two SVN options available in Preferences -> Team, one for Subversive preferences (which has been uninstalled and shouldn't be there anymore), and one for Sublipse preferences.
How to remove Subversive completely, so that there aren't any traces (such as Subversive's preferences screen) left in Eclipse?
Remove from Eclipse's plugins and features folders all files and folders like:
org.eclipse.team.svn*
org.polarion.eclipse.team.svn*
