Jenkins 用户文档（清理和通知）

清理和通知

由于管道的post部分保证在管道执行结束时运行，我们可以添加一些通知或其他步骤来执行最终、通知或其他管道结束任务。

Jenkinsfile (Declarative Pipeline)
pipeline {
    agent any
    stages {
        stage('No-op') {
            steps {
                sh 'ls'
            }
        }
    }
    post {
        always {
            echo 'One way or another, I have finished'
            deleteDir() /* clean up our workspace */
        }
        success {
            echo 'I succeeeded!'
        }
        unstable {
            echo 'I am unstable :/'
        }
        failure {
            echo 'I failed :('
        }
        changed {
            echo 'Things were different before...'
        }
    }
}

脚本管道（高级）：

Jenkinsfile (Scripted Pipeline)
node {
    try {
        stage('No-op') {
            sh 'ls'
        }
    }
    catch (exc) {
        echo 'I failed'
    }
    finally {
        if (currentBuild.result == 'UNSTABLE') {
            echo 'I am unstable :/'
        } else {
            echo 'One way or another, I have finished'
        }
    }
}

有很多方法可以发送通知，下面是一些演示如何将有关管道的通知发送到电子邮件、Hipchat聊天室或Slack通道的片段。

Email

post {
    failure {
        mail to: '[email protected]',
             subject: "Failed Pipeline: ${currentBuild.fullDisplayName}",
             body: "Something is wrong with ${env.BUILD_URL}"
    }
}

Hipchat

post {
    failure {
        hipchatSend message: "Attention @here ${env.JOB_NAME} #${env.BUILD_NUMBER} has failed.",
                    color: 'RED'
    }
}

Slack

post {
    success {
        slackSend channel: '#ops-room',
                  color: 'good',
                  message: "The pipeline ${currentBuild.fullDisplayName} completed successfully."
    }
}

现在，当事情失败、不稳定甚至成功时，团队会收到通知。
