好吧，我设法把一些东西凑在一起。我敢肯定，您可以更好地迭代数组，但这是我现在所拥有的：

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())
   }
}

@NonCPS
def getChangeLog(passedBuilds) {
    def log = ""
    for (int x = 0; x < passedBuilds.size(); x++) {
        def currentBuild = passedBuilds[x];
        def changeLogSets = currentBuild.rawBuild.changeSets
        for (int i = 0; i < changeLogSets.size(); i++) {
            def entries = changeLogSets[i].items
            for (int j = 0; j < entries.length; j++) {
                def entry = entries[j]
                log += "* ${entry.msg} by ${entry.author} \n"
            }
        }
    }
    return log;
  }
