As a Jenkinsfile developer

Given a Jenkins with the Gerrit Code Review plugin installed

When I write a declarative pipeline using a Gerrit SCM sourc

Then I am expecting it to run out-of-the-box with a declarative pipeline

And have the status of the pipeline execution reported to Gerrit

Background:

Because of the way it is currently implemented, it is compatible only with the scripted pipeline. Use the Pipeline Utility Steps as a reference and reimplement the Gerrit.groovy logic in a pure Java class.
