I have seen on svnkit website that the lastest version of SVN is not supported yet.
The last SVN version supported by SVNkit is 1.4.2 but i don't know if my version of JDevelopper uses the last JavaSVN (svnkit) library.
So, what is the highest version i can use with JDeveloper 10.1.3.2 ?
The plug-in that comes with JDeveloper specifically supports Subversion 1.3.2. Having said that, I have installed Subversion software version 1.4.3 on my windows laptop, and added the JavaHL library as well. Then, in JDeveloper, I selected "use native client." The overlay icons, version numbers, etc, are working fine.
Having said that, I've posted here before about using Subversion, and I personally do not check out/commit/etc from within JDeveloper - I use the command line, so I cannot comment on using the full features of the plug-in - I just use it to see a "general" status of my files in JDeveloper. So, the short answer: 1.3.2.
