was cached in the local repository 问题解决（maven）

今天在编译maven时报错：

[ERROR] Failed to execute goal on project logistics-service-api: Could not resolve dependencies for project com.baturu.logistics:logistics-service-api:jar:1.1.6_packageStatusFlow-SNAPSHOT: Failure
to find com....:logistics-service-api:jar:1.1.6_packageStatusFlow-SNAPSHOT in http://.../nexus/content/groups/public was cached in the local repository, resolution will

问题原因：

Maven默认会使用本地缓存的库来编译工程，对于上次下载失败的库，maven会在~/.m2/repository/ / / /目录下创建xxx.lastUpdated文件，一旦这个文件存在，一直到下一次nexus更新之前都不会更新这个依赖库。

解决办法：

网上的解决办法是：删除~/.m2/repository/ / / /目录下的*.lastUpdated文件，然后再次运行mvn clean install 编译工程。
可我试了，再次编译后~/.m2/repository/ / / /目录下又会有新的的*.lastUpdated文件

我想是这个文件导致了不能把本地的版本上传到私服，于是尝试把文件的后缀.lastUpdated去掉，使其变成一个jar文件

再次编绎项目，成功了，感动。
