I made a job with the following config :
parameters :

• GERRIT_REFSPEC default value refs/heads/release
• GERRIT_BRANCH default value $GERRIT_REFNAME

Git plugin config :
Url of repo : a right url
Refspec : $GERRIT_REFSPEC
Name or Repository : origin
Branch specifier : origin/$GERRIT_BRANCH

Gerrit Trigger config :

• Trigger on Change Merged , Ref Updated
• Dynamic config (..) (should be right)

My issue is on Ref Updated trigger, the log prints it fetches the origin/release (if I pushed directly on release) but in facts it does not get the checkout the last version.

eg : I updated an artifact version in a pom.xml, I push it by-passing gerrit, the refs updated triggers works and trigger my job but it does not take in account my pom.xml modification .
