maven执行报错resolution will not be reattempted until the update interval of nexus

maven在执行过程中抛错：

引用

... was cached in the local repository, resolution will not be reattempted until the update interval of nexus has elapsed or updates are forced -> [Help 1]

原因就是有些jar包没有完全下载完成，在编译的时候找不到jar包。只需要在配置文件中增加一个更新策略always就可以了。
找到你的conf/setting.xml
