solved, issue was since working in an organization( where proxy enabled), enabled proxy in settings.xml as given by maven in 5 min not working
解决了，问题是因为在组织中工作（启用了代理），在 5 分钟内由Maven提供的 settings.xml 中启用了代理 不起作用

Check the sha1 checksums in org/apache/maven/plugins/maven-resources-plugin/under your local repository and delete the maven-resources-plugindirectory if any of them are wrong. Or just delete the directory and let the maven to download it again.
检查org/apache/maven/plugins/maven-resources-plugin/本地存储库下的 sha1 校验和，maven-resources-plugin如果其中任何一个错误，则删除该目录。或者干脆删除目录，让maven重新下载。

Eclipse has a built-in Maven implementation. Try to compile the project from command line with the same Maven version as Eclipse has or set your Maven installation in Eclipse (Window / Preferences / Maven / Installations).
Eclipse 有一个内置的 Maven 实现。尝试使用与 Eclipse 相同的 Maven 版本从命令行编译项目，或者在 Eclipse 中设置您的 Maven 安装（Window / Preferences / Maven / Installations）。
