Hi,
we configured a new slave node connected to a Jenkins 2.8 master node but 
when we schedule a build we noticed an issue related to git client 
installed to the slave node. The exception reported is :

ERROR: Error cloning remote repo 'origin'

The command is empty but the git command is visible from client side. Could
