Question

您已经在jenkins的Post-build Actions中添加了以下groovy代码。

import java.util.*
import hudson.model.*

upstreamBuilds = manager.build.getUpstreamBuilds();
upstreamJob = upstreamBuilds.keySet().iterator().next();
lastUpstreamBuild = upstreamJob.getLastBuild();
if(lastUpstreamBuild.getResult().isBetterThan(manager.build.result)) {
lastUpstreamBuild.setResult(manager.build.result);
}

但是当我执行上面的代码时出现以下错误：

Recording fingerprints

由于我是groovy的新手，我不知道如何继续？

Answer 1

我相信这是因为你在一个没有元素的迭代器上调用next()。

我相信这会做同样的事情，但处理upStreamBuilds地图为空：

upstreamJob = manager.build.upstreamBuilds.find()
if( upstreamJob != null ) {
  lastUpstreamBuild = upstreamJob.key.lastBuild
  if( lastUpstreamBuild.result.isBetterThan( manager.build.result ) ) {
    lastUpstreamBuild.result = manager.build.result
  }
}

PS：您不需要使用groovy

导入java.util.*
