1. 新建流水線專案

2. 配置jenkins流水線專案觸發方式為Opened Merge Request Events

　　配置目標分支和生成token

3. gitlab新增jenkins專案的webhook

強制攔截配置

4. 配置流水線

pipeline {
    agent {
        node {
            // 節點名稱
            label 'node-1'
            customWorkspace "${env.JOB_NAME}/${env.BUILD_NUMBER}"
        }
    }
    options {
        gitLabConnection(
 
'gitlab')
    }
    stages {
        stage('PreEnv') {
            steps {
                script {
                    RECEIVER = RECEIVER
                }
                sh 'java -version'
            }
        }
        stage('Checkout') {

        }
    }
}

def send_email(String result, String receiver) {
    emailext (
        subject: "Build： ' + $result",
        body: '$DEFAULT_CONTENT',
        to: "$receiver"
    )
}

5. 測試， 通過自己的分支向master分支提交MR
