1、pipline语句超时、重试

pipeline {
    agent any
    stages {
        stage('Deploy') {
            steps {
                retry(3) {
                    sh './flakey-deploy.sh'
                }

                timeout(time: 3, unit: 'MINUTES') {
                    sh './health-check.sh'
                }
            }
        }
    }
}

2、执行带参数

parameters

pipeline{
    agent any
    parameters {
        string(name: 'P1', defaultValue: 'it is p1', description: 'it is p1')
        booleanParam(name: 'P2', defaultValue: true, description: 'it is p2')
    }
    stages{
        stage("stage1"){
            steps{
                echo "$P1"
                echo "$P2"
            }
        }
    }
}

3、异常处理

script里try，catch

pipeline {
    agent any
    stages {
        stage('stage 1') {
            steps {
                script{
                    try {
                        sh 'exit 1'
                    }
                    catch (exc) {
                        echo 'Something failed'
                        
                    }
                }
            }
        }
    }
}

4、邮件设置及发送预警

设置：
a、这里写上发件邮件地址

b、
密码填qq设置里的授权码
用户名也写上发件邮件地址
端口465


可以先验证下

c、
通知这里邮箱填写与上一步邮件通知里完全一样


这些触发结果需要通知设置

pipline发送预警邮件

在post后填写：

*****如果发送成功，但是邮件没收到，可以改下重新生成qq smtp授权码试试

pipeline{
    agent any
    parameters {
        string(name: 'P1', defaultValue: 'it is p1', description: 'it is p1')
        booleanParam(name: 'P2', defaultValue: true, description: 'it is p2')
    }
    stages{
        stage("stage1"){
            steps{
                echo "$P1"
                echo "$P2"
            }
        }
    }
    post {
            success {
                emailext (
                    subject: "SUCCESSFUL: Job",
                    body: """<p>SUCCESSFUL: 12312</p>${env.JOB_NAME} ${env.BUILD_NUMBER}，${env.BUILD_URL} """,
                    to: "[email protected],[email protected]",
                    from:"[email protected]"
                    
                   
                )
            }
            failure {
                emailext (
                    subject: "FAILED: Job ",
                    body: """<p>FAILED: Job213132</p>""",
                    to: "[email protected],[email protected]",
                    from:"[email protected]"
                    
                )
            }
        }
}

${env.JOB_NAME}
${env.BUILD_NUMBER}
${env.BUILD_URL}
