8.jenkins调用maven工具管理java代码实现滚动发布

1.配置多jdk环境

2.配置多maven环境

3.配置maven项目

3.1 配置部署主机

[root@jenkins war_update]# cat hosts_test 
[webservice]
192.168.1.191
[root@jenkins war_update]# cat hosts_prod 
[webservice]
192.168.1.43
192.168.1.254

3.2 配置git commit id

3.3 配置git仓库

3.4 配置build参数

3.5 构建完毕后调用ansible自动化工具部署
