Jenkins Pipeline SSH Publisher环境变量跨阶段步骤传递

最近在编写Jenkins流水线，需要在其它阶段计算环境变量，然后在下一阶段使用到的sshPublisher用到该变量。 经调试很多次都没成功，最后发现关键在于命令外围需要用双引号括起来。以下是具体例子。

environment {

   DOCKER_ENV_CMD=''

   DOCKER_HOST_CMD=''

   DOCKER_RUN_CMD=''

}

stage ('预处理') {

    steps {

        script {

            def dockerRunCmd = sh(script: "echo -e \"docker run -d -p $docker_node_port:$docker_app_port -v /etc/localtime:/etc/localtime -v $app_log_path:/app/logs ${DOCKER_ENV_CMD} ${DOCKER_HOST_CMD} --name $docker_container_name $docker_image_url:$docker_image_version\"", returnStdout: true).trim()

            DOCKER_RUN_CMD = dockerRunCmd

            echo "=================================="

            echo " DOCKER_RUN_CMD => ${DOCKER_RUN_CMD}"

            echo "=================================="

        }

    }

}



    stage ('重启应用') {

        steps {

            sshPublisher(publishers: [sshPublisherDesc(configName: 'test-app', transfers: [sshTransfer(cleanRemote: false, excludes: '', execCommand: """sudo docker rm -f $docker_container_name

            sudo ${DOCKER_RUN_CMD}""", execTimeout: 120000, flatten: false, makeEmptyDirs: false, noDefaultExcludes: false, patternSeparator: '[, ]+', remoteDirectory: '', remoteDirectorySDF: false, removePrefix: '', sourceFiles: '')], usePromotionTimestamp: false, useWorkspaceInPromotion: false, verbose: false)])

        }

    }
