Error occured beacuse of Old cache of Maven tool is present in your directory. So you must delete it. Go to C\User\"your user name"\m2 then delete it.
由于 Maven 工具的旧缓存存在于您的目录中，因此发生错误。所以你必须删除它。转到 C\User\"您的用户名"\m2 然后将其删除。

You can use -Uparameter to force a check for the updated releases and snapshots on remote
repositories, and resolve this issue.
您可以使用-U参数强制检查远程存储库上的更新版本和快照，并解决此问题。
Actually you can find this solution by using mvn -hto show Maven help.
实际上，您可以通过使用mvn -h来显示 Maven 帮助来找到此解决方案。
