或者报错：

resolve dependencies for project common-core:jar:{revision} : Failure 
to find common-core:jar:1.0 in http://maven.XXXXX/repository/maven-

原因：端口占用

出现原因

8080服务启动的时候，使用git还原commit记录【慎用，还原太远git代码丢失，从idea本地找回代码】，导致8080端口卡到了，出现了大量的8080端口服务。

处理方式

-- 查看指定端口对应的pid
netstat -ano | findstr 8080 
-- 关闭pid的进程，-F强制关闭，卡到了不给关。
taskkill /pid [查到的pid号] -F
例如：taskkill /pid 12356 -F

说明

common-core:jar为我自己本地打包的依赖，启动会显示找不到依赖，因为使用了flatten-maven-plugin来管理父子依赖，才开始报错版本会不显示，显示为下面的报错信息，初以为是插件的问题，去掉以后还是报错误，联想到启动类想到了端口，才试着去查一下端口，结果发现大量的8080端口，需要全部杀掉就可以运行了。

另外：报错信息可能不完善，有略微区别，大致报错信息是这个，这个信息是从相同报错的仁兄那里复制过来的，谢谢！ ^ v ^
