本篇内容介绍了"通过jenkins发布java项目到目标主机上的步骤是什么"的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！

发布java项目的步骤：

• 拉取代码并打包

• mvn clean package

• 备份目标服务器上已有的要发布项目

• 将包传到目标服务器的webapss目录中

• 需做免密登录

• 重启目标服务器的tomcat服务

• 修改项目的配置

• 重启目标服务器的tomcat服务

项目要求:

两台主机上分别安装jenkins，tomcat

jenkins主机上操作
