Jenkins терпит неудачу с github «git clone»

Когда я собираю Jenkins, он выдает эту ошибку. Есть идеи?

ERROR: Error cloning remote repo 'origin' : Could not clone git@github.com:test/test.git
ERROR: Cause: Error performing command: git clone --progress -o origin 

git@github.com:test/test.git /var/lib/jenkins/jobs/test/workspace
Command "git clone --progress -o origin git@github.com:test/test.git 
/var/lib/jenkins/jobs/test/workspace" returned status code 128: Initialized empty Git
