编译Maven项目时报错，was cached in the local repository, resolution will not be reattempted until the update interval of local-nexus-mirror has elapsed or updates are forced
错误信息：
[ERROR] Failed to execute goal on project platform-xxx: Could not resolve dependencies for project com.frond.xxx:platform-xxx:jar:0.1: Failed to collect dependencies at com.trip.public:common-utils:jar:1.2.0-SNAPSHOT: Failed to read artifact descriptor for com.trip.public:common-utils:jar:1.2.0-SNAPSHOT: Failure to find com.trip.public:platform-common:pom:0.6 in http://nexus.tool.cn/repository/ was cached in the local repository, resolution will not be reattempted until the update interval of local-nexus-mirror has elapsed or updates are forced -> [Help 1]
问题原因：
1、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.../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。
2、maven包管理混乱，下载失败
解决方法：
方法一：
删除.../repository/<group>/<artifact>/<version>/目录下的*.lastUpdated文件，重新编译项目。
方法二：
修改settings.xml文件，仓库添加?<updatePolicy>always</updatePolicy>，强制每次都更新依赖库。
