配置流水线

Pipeline script:

pipeline {
    agent any

    stages {
        stage('pull') {
            steps {
                git branch: 'release/5.1-prod-merge-20240301_fagnbao_refactor', credentialsId: '75c1d879-bb95-4fca-8dc5-df7b4ea06e3c', url: 'http://gitlab.xxxxxx.cn/chengduteam/rd/yuexiu-crm.git'
            }
        }
        
        stage('build') {
            steps {
                sh "/var/jenkins_home/apache-maven-3.6.3/bin/mvn clean package -pl yx-gateway -am -Dmaven.test.skip=true"
                echo "Compile complete."
            }
        }
        
        stage('deploy') {
            steps {
                sshagent(['ssh_root_key']) {
                    script {
                        sh 'ssh [email protected] "bash /data/docker_data/jenkins/jenkins_home/DockerFiles/yx-gateway/deploy.sh"'
                    }
                }
            }
        }
    }
}

执行上方 Pipeline script 需先安装插件 SSH Agent，然后配置 Jenkins 的 SSH 密钥凭证，最后在脚本的 sshagent 项里添加上相关凭证
