idea maven找不到依賴

相信你們開發中老是遇到maven爆紅的狀況，其中的緣由可能有maven倉庫源加載緩慢，能夠在項目中配置本身的私服或者配置國內的景象源，經常使用鏡像源maven的settings文件配置

配置好以後將ide的maven路徑修改

        刷新maven配置

        上述操做以後仍是爆紅，實際上maven倉庫裏面有了對應的jar包了，此時只能命令行執行mvn clean compile 或者mvn clean install 看控制檯錯誤，檢查報錯的jar包是否是本身公司的內部jar包，若是是，找到對應jar包的版本路徑和實際maven的路徑 版本是否一一對應

        上圖中的common 1.0在我本地不存在，最後找到pom文件檢查，發現如今的版本是1.0-SNAPSHOT,改完版本從新執行maven clean installl就能夠了。爲何別人的能夠，是由於別人在改版本以前已經編譯過了，有了對應的jar包在本地倉庫了因此別人的正常你的不正常，加載緩慢重啓ide從新更新便可。
