idea maven找不到依赖

相信你们开发中老是遇到maven爆红的状况，其中的缘由可能有maven仓库源加载缓慢，能够在项目中配置本身的私服或者配置国内的景象源，经常使用镜像源maven的settings文件配置

配置好以后将ide的maven路径修改

        刷新maven配置

        上述操做以后仍是爆红，实际上maven仓库里面有了对应的jar包了，此时只能命令行执行mvn clean compile 或者mvn clean install 看控制台错误，检查报错的jar包是否是本身公司的内部jar包，若是是，找到对应jar包的版本路径和实际maven的路径 版本是否一一对应

        上图中的common 1.0在我本地不存在，最后找到pom文件检查，发现如今的版本是1.0-SNAPSHOT,改完版本从新执行maven clean installl就能够了。为何别人的能够，是由于别人在改版本以前已经编译过了，有了对应的jar包在本地仓库了因此别人的正常你的不正常，加载缓慢重启ide从新更新便可。
