I've successfully installed Subclipse through Eclipse's Help > Install New Software....
When I go to Java perspective > Package Explorer view > Team > Share Project and select SVN, I get:
org.tigris.subversion.javahl.ClientException: svn: The path '\path\to\project' appears to be part of Subversion 1.7 (SVNKit 1.4) or greater
Seems a problem with version mismatch, get a proper version of subclipse
From subclipse site:
You might have to uninstall the previous version of subclipse (and SVNKit) before installing the new version.
