Jenkinsfile-获取内部版本之间的所有更改 [英] Jenkinsfile - get all changes between builds

问题描述

参考此问题在使用多分支管道时是否可以从中获取等效信息?具体来说-自上次成功构建以来的提交列表.

With reference to this question is there a way to get the equivalent information from when using the mult-branch pipeline? Specifically - the list of commits since the last successful build.

当前，我们使用以下

def scmAction = build?.actions.find { action -> 
    action instanceof jenkins.scm.api.SCMRevisionAction
}
return scmAction?.revision?.hash

，但是如果推送了多个提交，这只会返回触发构建的最后一个提交.我接受新分支的第一个构建可能会含糊不清，但是获取在可能的情况下触发构建的提交列表 将非常有用.

but this only returns the last commit that triggered the build if multiple commits were pushed. I accept that the very first build of a new branch might be ambiguious but getting a list of commits that triggered the build when possible would be very useful.

推荐答案

我找到了一个似乎对我们有用的解决方案.它围绕着获取currentBuild提交哈希值，然后是lastSuccessfulBuild提交哈希值.首先，我们编写了一个实用程序方法来获取给定Jenkins构建对象的提交哈希:

I have found a solution that seems to work for us. It revolves around getting the currentBuild commit hash and then the lastSuccessfulBuild commit hash. First we wrote a utility method for getting a commit hash of a given Jenkins build object:

def commitHashForBuild(build) {
  def scmAction = build?.actions.find { action -> action instanceof jenkins.scm.api.SCMRevisionAction }
  return scmAction?.revision?.hash
}

然后使用它来获取lastSuccessfulBuild的哈希值:

then use that to get the lastSuccessfulBuild's hash:

def getLastSuccessfulCommit() {
  def lastSuccessfulHash = null
  def lastSuccessfulBuild = currentBuild.rawBuild.getPreviousSuccessfulBuild()
  if ( lastSuccessfulBuild ) {
    lastSuccessfulHash = commitHashForBuild(lastSuccessfulBuild)
  }
  return lastSuccessfulHash
}

最后在sh函数中将二者结合起来以获取提交列表

finally combine those two in a sh function to get the list of commits

  def lastSuccessfulCommit = getLastSuccessfulCommit()
  def currentCommit = commitHashForBuild(currentBuild.rawBuild)
  if (lastSuccessfulCommit) {
    commits = sh(
      script: "git rev-list $currentCommit \"^$lastSuccessfulCommit\"",
      returnStdout: true
    ).split('\n')
    println "Commits are: $commits"
  }

然后，您可以根据构建需要使用commits数组查询Git中的各种内容.例如.您可以使用此数据获取自上次成功构建以来所有已更改文件的列表.

you can then use the commits array to query various things in Git as your build requires. E.g. you can use this data to get a list of all changed files since the last successful build.

我已将其放入完整的示例Jenkinsfile 要点以显示其如何在上下文中融合在一起

I have put this into a complete example Jenkinsfile Gist to show how it fits together in context.

一个可能的改进是使用Java/Groovy本地Git库，而不是使用sh步骤.

A possible improvement would be to use a Java/Groovy native Git library instead of shelling out to a sh step.
