I'm getting
org.tmatesoft.svn.core.SVNException: svn: URL 'svn://localhost/trunk' doesn't exist
because I'm using an SVN server version 1.7

I hear that "SVNKit 1.3.7 (released December 6th) should work with 1.7"
Specifically I read that in this discussion:
http://jenkins.361315.n4.nabble.com/Jenkins-cannot-connect-to-SVN-1-7-repositories-td4167322.html
(please go all the way to the bottom of the page).

I've confirmed this at the SVNKit web site:
"6 Dec 2011, 19:02, version 1.3.7
Changelog:
+ 1.7 Subversion servers compatibility issues fixed."
http://svnkit.com/download.php

Is it easy to upgrade the tweaked SVNKit inside the Subversion Plugin to upgrade it to SVNKit 1.3.7 ?
