was cached in the local repository, resolution will not be reattempted until the update interval of fintech has elapsed or updates are forced

今天使用命令mvn compile编译maven项目时提示错误信息，错误信息如下： 

1 2 3 4

[ERROR] Failed to execute goal on project <project_name>: Could not resolve dependencies for project com.xxx.xxx:<project_name>:jar:1.0.7: Failure to find com.xxx.xxx:obj-test-client:jar:1.1.1 in http://maven-nexus.xxx.com/repository/maven-public/ was cached in the local repository, resolution will not be reattempted until the update interval of fintech has elapsed or updates are forced -> [Help 1]

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/<group>/<artifact>/<version>/目录下创建xxx.lastUpdated文件，一旦这个文件存在，那么在直到下一次nexus更新之前都不会更新这个依赖库。

解决办法：

删除v~/.m2/repository/<group>/<artifact>/<version>/目录下的*.lastUpdated文件，然后再次运行mvn compile编译工程。

Jenkins构建时报错：

通过jenkins编译时报此错，我的maven安装目录/opt/maven ，解决方法如下：

发现obj-test-client-1.1.1.jar下载到本地时失败，从提示可知是本地仓库的缓存（cached）造成，于是我删除目录/opt/maven/repo/<group>/obj-test-client/1.1.1后Jenkins重新构建（或在项目目录 mvn 重新编译）即可编译成功！ 

注意你要确定远程仓库中存在此jar（obj-test-client-1.1.1.jar）包
