如何在Jenkinsfile中为失败的构建执行操作 [英] How to perform actions for failed builds in Jenkinsfile

问题描述

我想告诉我们的Atlassian Stash实例，构建失败（或者回滚）如果在Jenkinsfile中构建失败，通过在正确的URL处执行 curl ）。

基本上，当设置构建状态时，

我应该使用 try {} catch（）吗？如果是这样，我应该捕获什么样的异常类型？

解决方案

我目前也在寻找解决这个问题的方法。到目前为止，我能想到的最好的方法是创建一个包装函数，它在try catch块中运行管道代码。如果您还想通知成功，则可以将Exception存储在变量中，并将通知代码移至finally块。另外请注意，您必须重新抛出异常，以便Jenkins认为构建失败。
$ b

  pipeline（'linux'）{
 stage'Pull'可能有些读者会发现一个更优雅的方法来解决这个问题。 '
 stage'Deploy'
 echo部署
抛出FileNotFoundException（Nothing to pull）
 // ... 
} 
 
 def pipeline（String label，Closure body）{
 node（label）{
 wrap（[$ class：'TimestamperBuildWrapper']）{
 try {
 body。 call（）
} catch（Exception e）{
 emailext subject：$ {env.JOB_NAME}  -  Build＃$ {env.BUILD_NUMBER}  -  FAILURE（$ {e.message}）！， to：[e-mail]，body：...
 throw e; //重新抛出，因此构建被认为是失败的
 
 
 
 
 code $ pre $ $ b
Is there a way to perform cleanup (or rollback) if the build in Jenkinsfile failed?

I would like to inform our Atlassian Stash instance that the build failed (by doing a curl at the correct URL).

Basically it would be a post step when build status is set to fail.

Should I use try {} catch ()? If so, what exception type should I catch?
解决方案
I'm currently also searching for a solution to this problem. So far the best I could come up with is to create a wrapper function that runs the pipeline code in a try catch block. If you also want to notify on success you can store the Exception in a variable and move the notification code to a finally block. Also note that you have to rethrow the exception so Jenkins considers the build as failed. Maybe some reader finds a more elegant approach to this problem.
pipeline('linux') {
    stage 'Pull'
    stage 'Deploy'
    echo "Deploying"
    throw new FileNotFoundException("Nothing to pull")
    // ... 
}

 def pipeline(String label, Closure body) {
     node(label) {
        wrap([$class: 'TimestamperBuildWrapper']) {
            try {
                body.call()
            } catch (Exception e) {
                emailext subject: "${env.JOB_NAME} - Build # ${env.BUILD_NUMBER} - FAILURE (${e.message})!", to: "[e-mail]",body: "..."
                throw e; // rethrow so the build is considered failed                        
            } 
        }
    }
}
