I'm getting the same error with version 1.480.2. It doesn't matter if there were any changes or not in the repo, the same error comes always, almost: strangely the build succeeded once without this error.

I'm getting the same thing. I made it work but you need to go in and manually remove the Merge info on the branch for it to work.

I try to remove merge info manually still it is not working i am getting same error

I've had the same issue and investigated a little bit. Seems that ubuntu 12.04 and 11.10 uses svnkit 1.3.5 while 12.10 and 13.04 uses svnkit 1.7.5. Looking at the SVNException code in old svnkit, it does not check for null errorMessages, so it will throw an NPE exception. In newer svnkit, they actually check for null and handle it.

Adding handling for null in this plugin is one way to go, or update your server software as a workaround

Hi
Oscar

I am using windows and try to use these plug in can you please let me know what software i need updatd. does these need to be updated on build server or subversion server.
Thank you so much for your help

Thx
C

I should add, I have not been able to get svnkit updated yet as this is a production server. Looking at the code however, it indicates that null references are at least handled in svnkit 1.7.5 etc.

Chirag, I'm not sure how jenkins is managed on a windows machine, but I assume you have svnkit installed somewhere on the server (http://svnkit.com/). It might come with the jenkins package, or subversion plugin, or some other plugin possibly.

Hello,

I resolved the problem thanks to this blog : http://adam-payne.blogspot.fr/2013/07/jenkins-svnmerge-plugin.html

The guy fixed the bug into the code, and he left available in github, but not compiled

So I attach the plugin compiled, you just have to delete the old plugin (directly in jenkins), and add the hpi file as plugin in jenkins (Managment -> Plugin -> Advanced)

And enjoy it

The issue has been resolved while fixing JENKINS-12495.
