Jenkins Pipeline：根据参数设置环境变量

pipeline {
agent any
environment {
    //以上自定义的参数
    project =  "$params.PROJECT"
}

stages {
    stage('获取端口'){
        steps{
         script{
            switch(project)
            {
                case 'kangaroo-bill':
                  env.SERVICE_PORT = '9100'
                  break
                case 'kangaroo-design-process':
                  env.SERVICE_PORT = '9015'
                  break
            }

               sh 'echo $SERVICE_PORT'

         }
        }
    }
    stage('更新或回滚'){
        steps{
          script{
                        //进入192.168.80.232服务器执行发布脚本
                        sh 'ssh root@192.168.80.232  "/deploy/bin/publish.sh   ${PROJECT}  ${SERVICE_PORT}"'

                }
       }
