It would be nice to restart from a checkpoint, 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.

This can be accomplished by storing the original build number before creating a checkpoint, and then comparing the stored build number against the current build number whenever you want to know if the build has resumed:

def origBuildNumber = BUILD_NUMBER
checkpoint 'about to run'
def platforms
if (origBuildNumber == BUILD_NUMBER) {
  platforms = 'amd64,linux,solaris,NT'
} else {
  // resumed build
  def selections = input …
  platforms = …using selections…
node {
  sh "make clean all -plats=${platforms}"
