pipeline 中使用 if 语句

pipeline {
    
    //创建 jenkins 参数
    parameters {

        string(name: 'open_log', defaultValue: params.open_log, description: 'log-on: 加入 online ; log-off: 不加 online')

            steps {

                sh "echo ${params.open_log}"

                script {

                    if (params.open_log.trim() == "log-on") {
                        env.RUN_CMD = "on"
