Subject: Optimize the jjb-deploy trigger regex
X-Git-Tag: v0.34.0~8^2
X-Git-Url: https://gerrit.linuxfoundation.org/infra/gitweb?a=commitdiff_plain;h=c3128e6979246c6dadb83be4a14b5179b5d53721;p=releng%2Fglobal-jjb.git

Optimize the jjb-deploy trigger regex

Optimize the jjb-deploy trigger regex to trigger the job _only_
when the Gerrit CR comment is intended as a command.

The `jjb-deploy` job presently gets triggered and is waste of infra
resources when the keyword is intended as comment in Gerrit.
