Used to inject a message into the Gerrit Trigger plugin's build summary comment at the end of all builds.
One example for this feature is to use it to return the log location of a build in cases where logs and / or archives are shipped off of Jenkins to another service elsewhere.
Example Message:
Logs: https://logs.example.org/jenkins/jenkins001/$JOB_NAME/$BUILD_NUMBER
Example Result:
Patch Set 1: Verified+1 Build Unstable https://ci.example.org/jenkins/job/example-job-a/123/ : UNSTABLE Logs: https://logs.example.org/jenkins/jenkins001/exampe-job-a/123 https://ci.example.org/jenkins/job/example-job-b/456/ : SUCCESS Logs: https://logs.example.org/jenkins/jenkins001/example-job-b/456
