False failures on checkstyle in Jenkins-gerrit hook

[Allon Mureinik]

Hi guys,

Lots, and I mean LOTS of recent ovirt-engine patches are falsely failing the checkstyle gerrit-hook (e.g.,: http://gerrit.ovirt.org/#/c/18854/)

>From the job's output it seems that the slave simply can't clone the git repo.
E.g. http://jenkins.ovirt.org/job/ovirt_engine_sanity_compile_checkstyle_gerrit/7643/:

Can you please take care of this?
It's causing a lot of noise and false alarms on gerrit.


Thanks,
