I know that the thread is out of date and almost out of date, but it has not stopped from people like me, landing here, in search of a solution to this popular Jenkins problem. So now the problem is solved. I am posting an answer for future use: -
An initial search gives this problem due to an error in some version of the SVN plugin, so the obvious solution is to change this plugin, the same is indicated in the links given by @ChrisH. His links were a great help. Thus, you can update the svn plugin using the following two methods: -
- Go to plugin management and install the update there.
- Download the * .hpi file from this link and put the * .hpi file in the $ JENKINS_HOME / plugins / folder. If you do not know where the $ JENKINS_HOME folder is located than most chances are, it will be a hidden folder in your home directory (for Linux).
After updating the plugin, you need to restart the Jenkins so that the new plugin can take effect.
However, if you recently downloaded jenkins, you may not need to follow the above process. Just go to Jenkins-> Configure System Management and change the version of SVN (to version 1.6) in the combo box.
Good luck
