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

解决办法：命令中增加个参数U，如下： mvn -U clean install -Dmaven.test.skip=true

use -U parameter to force a check for the updated releases and snapshots on remote repositories, and resolve this issue.

Actually you can find this solution by using mvn -h to show Maven help

查资料看着还有的说删掉*.lastUpdated文件，但我没看到这样的文件。
