Question

理想情况下，我想在声明性Jenkins管道中处理失败并向委员会发送电子邮件。但我根本无法上班。我有以下脚本：

pipeline {

    agent any

    stages {
        stage('Prepare') {
            steps {
                cleanWs
                checkout scm
            }
        } 
    }

    post {
        always {
            echo '============'
            echo 'In Post part'
            echo '============'
            echo currentBuild.result  // this prints null
        }
    }
}

在我的Jenkins版本中cleanWs()未定义，因此构建失败并显示：

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 11: Expected a step @ line 11, column 17.
                   cleanWs
                   ^

Finished: FAILURE

但正如你所看到的，没有

============
In Post part
============

因此post always未执行。

Answer 1

根本没有执行您的管道，请参阅错误：MultipleCompilationErrorsException: startup failed:。由于甚至无法编译管道脚本，因此作业根本无法启动，因此显然不会执行post块。由于无法编译源代码，因此无论如何jenkins都不知道任何post块。

Post始终未在声明性管道异常上执行
