如何检测Jenkins声明性管道中哪个并行阶段失败？

Question

我的Jenkins流水线并行运行多个任务。似乎如果一个阶段失败，所有后续阶段将运行其＜code＞failure＜/code＞post块（无论它们是否实际失败）。我不知道这是故意的还是我做错了什么。

注意:这个管道运行在一个Windows节点上，因此< code>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，这表明对这两个步骤都执行了< code>failure条件！

对于我来说，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？

看起来这是一个关于声明性管道的已知错误。我不得不放弃使用内置的帖子-

1. 您必须捕获然后重新引发错误，以使阶段相应地失败。
2. UI 可能会有点混乱，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）。
3. 代码的可读性稍差。

这段代码工作正常。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)
                            }
                        }
                    }
                }
            }
        }
    }
}
