java 程序发布步骤：
1、拉取代码并打包
2、备份源程序
3、拷贝新程序到服务器的webapps目录中，停一会修改配置
4、重启tomcat
5、验证

接收端创建一个文件夹来存放备份文件
[root@server ~]# mkdir /opt/backup [root@server ~]# ls /opt/backup/
脚本：
pipeline {
agent any
stages {
stage('Build') {
steps {
// Get some code from a GitHub repository
git 'https://gitee.com/forgotten/tomcat-java-demo.git'
// Run Maven on a Unix agent.
sh "mvn -Dmaven.test.failure.ignore=true clean package"
sh "mv target/ly-simple-tomcat-0.0.1-SNAPSHOT.war target/mywxy.war"
// To run Maven on a Windows agent, use
// bat "mvn -Dmaven.test.failure.ignore=true clean package"
