Hi Max,
When jenkins build fails there's a link to particular build - if you follow it you can click "retrigger" in the left menu for particular build in jenkins (provided you have account).
I followed the link mentioned in Gerrit for the failed build http://jenkins.osmocom.org/jenkins/job/osmo-pcu-gerrit/81/ but I am not able to locate the "retrigger" button. Can you please help?
Thanks, Aravind Sirsikar
