jenkins - 如何检测 Jenkins 声明式管道中哪个并行阶段失败？

Question

我的 Jenkins 管道并行运行多个任务。似乎如果一个阶段失败，所有后续阶段都将运行它们的 failure发布阻止(无论他们是否真的失败了)。我不知道这是设计使然还是我做错了什么。

注意:此管道在 Windows 节点上运行，因此 bat('exit /b 1')

pipeline {
    agent any

    stages {
        stage('Parallel steps') {
            parallel {
                stage('Successful stage') {
                    steps {
                        script { sleep 10 }
                    }
                    post {
                        failure {
                            echo('detected failure: Successful stage')
                        }
                    }
                }
                stage('Failure stage') {
                    steps {
                        script { bat('exit /b 1') }
                    }
                    post {
                        failure { 
                            echo('detected failure: Failure stage')
                        }
                    }
                }
            }
        }
    }
}

在上面的管道中，只有“失败阶段”失败，但在输出中我看到了这一点，表明 failure两个步骤都有条件执行!

[Successful stage] Sleeping for 10 sec
[Failure stage] [test] Running batch script
[Failure stage] D:\workspace>exit /b 1 
Post stage
[Pipeline] [Failure stage] echo
[Failure stage] detected failure: Failure stage
[Failure stage] Failed in branch Failure stage
Post stage
[Pipeline] [Successful stage] echo
[Successful stage] detected failure: Successful stage
ERROR: script returned exit code 1
Finished: FAILURE

我检测哪个并行阶段失败并将其报告给整个管道的最佳方法是什么？

看起来这是一个 known bug使用声明式管道。我不得不放弃使用内置的 post->failure 块并使用 try/catch 代替，它有自己的问题:

您必须捕获并重新抛出错误才能使阶段适本地失败。

UI 可能会有些困惑，因为失败的步骤不再以红色突出显示(但错误消息仍在日志中)。

代码可读性稍差。

此代码正常工作。只有失败的阶段回显“检测到的失败”而不是两者。

pipeline {
    agent any

    stages {
        stage('Parallel steps') {
            parallel {
                stage('Successful stage') {
                    steps {
                        script {
                            try {
                                sleep 10 
                            } catch (e) {
                                echo('detected failure: Successful stage')
                                throw(e)
                            }
                        }
                    }
                }
                stage('Failure stage') {
                    steps {
                        script {
                            try {
                                bat('exit /b 1')
                            } catch (e) {
                                echo('detected failure: Failure stage')
                                throw(e)
                            }
                        }
                    }
                }
            }
        }
    }
}
