问题分析

由于近期公司内部maven仓库关了，而Jekins部署的服务器只能访问内网，于是导致了上述问题。外网访问不了那就把依赖先下载下来然后上传到jekins服务器即可。

 

解决过程

1.上传相关依赖到Jekins服务器，随便找一个目录存放即可（这里我放在了C:\.m2\repository）

2.修改Jekins编译环境配置，maven编译指令添加参数 -Dmaven.repo.local=C:\.m2\repository（等号后面是刚才依赖上传到的目录）

3.正常情况下完成上述两个步骤就可以了。但是今天遇到了一个新问题，上传之后明明本地已经有依赖了，maven还是一直去远程仓库下载依赖。所以我把所有C:\.m2\repository下所有的_remote.repositories文件全部剪切，丢进垃圾桶。

再回到Jekins重新Build一下。
