Up to Jenkins 1.460, its Subversion plugin 1.39 hasn't supported Subversion 1.7, so you may hit error like below screen shot :
1. Install the latest CollabNet Subversion Client to the server, which provides svn command-line tool.
It works because the shell will use the system variable where PATH includes the latest CollabNet path rather than the old svn path used by Jenkins.
Jenkins issue 11381 describes it.
