      As system user jenkins (which runs Jenkins) I am perfectly able to run that command:

      $ git --version
git version 1.7.9.5

      Cloning worked before, but all of a sudden the above error occurs.

      I tried both to specify the full path to the git executable (/usr/bin/git) and to specify the name of the executable only (without path: git). However, without success.
