突发奇想让开发在测试环境实现服务的四个状态
一个pipeline的四个功能块
前提了解pipeline的语法

jenkins pipeline基础语法与示例

pipeline {

       PROJECT_NAME="imin"
	   //相对编译目录的jar包路径 
	   JAR_PATH = "target/${PROJECT_NAME}.jar"
	   //目标主机 jar包目录路径
	   DEST_HOST_JAR_DIR = "/home/java/${PROJECT_NAME}/"
	   //目标主机ip 或者 主机名
	   DEST_HOST="im"
	   //jar包使用的配置
	   ACTIVE_NAME = "t"
	   //ssh到目标主机的用户名
	   SSH_USER = "centos"
	   //ssh到目标主机的端口
	   SSH_PORT = "6"
	   //jar包启动监听的端口
	   SERVER_PORT="90"
