This plugin adds the ability to directly merge Subversion branches in Jenkins. See http://code.google.com/p/jigomerge/
Configure your Subversion repository in the Source Code Management section : this is the branche you want to merge to.
In the Build Triggers section, set a value in Build periodically. Do not use Poll SCM !
Advice : The merge to be effective should be run as often as possible. For exemple set the Build periodically to every hour. This will prevent conflicts as much as possible.
In the Build section, choose Perform svn merge with Jigomerge.
