Issue

It would be nice to restart from a checkpont, and mutate a build parameter. The use case here is someone clicks “run from this checkpoint” and unchecks the platforms (on by default) they do not wish to rerun.

Environment

• CloudBees Jenkins Platform
• Pipeline Plugin

Resolution

This could be handled to the extent that the original property of the return value of the step should be non-null if and only if resuming.

This can be accomplished by doing the following in your Pipeline script:

def cp = checkpoint 'about to run'
def platforms
if (cp.original == null) {
  platforms = 'amd64,linux,solaris,NT'
} else {
  def selections = input …
  platforms = …using selections…
}
sh "make clean all -plats=${platforms}"
