业务场景

settings.xml种配置了私服，但是有些依赖私服上没有，通过同事拷贝过来的。但是用maven打包时报红了。

错误提示

Idea Maven错误：was cached in the local repository, resolution will not be reattempted until the update

was cached in the local repository, resolution will not be reattempted until the update interval of io.spring.repo.maven.release has elapsed or updates are forced

分析过程

1. 按照提示，查找本地repository中是否有缺失的jar，但jar都是有的，同事拷贝的都有jar文件
2. 参考几篇文章：maven依赖报红。解决本地有jar包，idea无法加载
   _remote.repositories文件的作用
   使用Maven管理项目时，明明本地仓库有对应的jar包，但还是报找不到
   快速清理本地仓库的文件

解释：maven3.x版本从远程库下载依赖后，会生成对应的_remote.repositories文件，标示该资源的来源。如果你有这个文件_remote.repositories，那就不会访问本地了，会去远程上找。必须远程上有才行，否则就会报错。

而我们的私服是没有依赖的，直接拷贝到的本地。

解决办法

删除对应仓库中的_remote.repositories文件

如果多可以使用快速清理本地仓库的文件
