Resolution

This is related to a permission issue. Jenkins' user needs write permission for SVN to your project directory. Please check the permissions of your project directory.

To recursively change permissions to allow Jenkins to write to your project you can run:

sudo chown -R MY_JENKINS_USER:MY_JENKINS_GROUP MY_PROJECT▼

where MY_JENKINS_USER and MY_JENKINS_GROUP should be replaced with the user and group that you use for Jenkins and MY_PROJECT replaced with your project directory.
