Using the UI Pipeline Snippet generator, JENKINS_URL/job/JOB_NAME/pipeline-syntax/

generates an unusable block of code:

step([$class: 'ViolationsToGitHubRecorder', config: <object of type org.jenkinsci.plugins.jvctg.config.ViolationsToGitHubConfig>])

It's a good thing the documentation in the github project is thorough. Even still, it still took many tries to get the authentication working correctly.
