问如何在jenkins pipeline中获得自上次成功构建以来的更改？

EN

node('Android') {
  passedBuilds = []

  lastSuccessfulBuild(passedBuilds, currentBuild);

  def changeLog = getChangeLog(passedBuilds)
  echo "changeLog ${changeLog}"
}

def lastSuccessfulBuild(passedBuilds, build) {
  if ((build != null) && (build.result != 'SUCCESS')) {
      passedBuilds.add(build)
      lastSuccessfulBuild(passedBuilds, build.getPreviousBuild())
   }
}
