Script Security and Jenkinsfile

[Mark Bidewell]

I am trying to write a Jenkinsfile for a project.  The script security plugin is becoming a real pain.  It seems the only way to add methods and operations is to run the job repeatedly failing each time and manually approve each failure.  Needless to say this is a time-consuming process for all but the most trivial build scripts.  Is there a better way to handle this?
