How to get the changes since the last successful build in jenkins pipeline?

Question

Anyone have a Jenkins Pipeline script that can stuff all the changes since the previous successful build in a variable? I\'m using git and a multibranch pipeline job.

This is what I've used:

def listFilesForBuild(build) {
  def files = []
  currentBuild.changeSets.each {
    it.items.each {
      it.affectedFiles.each {
        files << it.path
      }
    }
  }
  files
}

def filesSinceLastPass() {
  def files = []
  def build = currentBuild
  while(build.result != 'SUCCESS') {
    files += listFilesForBuild(build)
    build = build.getPreviousBuild()
  }
  return files.unique()
}

def files = filesSinceLastPass()
