我已经使用 m2 eclipse 工具创建了一个项目，并选择了 Web 应用程序原型，如果我尝试打包这个空应用程序，我会收到构建失败消息

现在我已经尝试更新存储库等，但我没有运气。
根据建议，我尝试更新插件注册表，但我的文件系统上没有这样的文件 pugin-registry.xml 。
而且它在 eclipse 中构建得很好，但在 command 中失败了，所以我猜测它们都使用不同的版本。如何解决这个问题？
尝试使用-cpu旗帜。输出来自mvn -help:
usage: mvn [options] [<goal(s)>] [<phase(s)>]
Options:
-cpu,--check-plugin-updates Force upToDate check for any
relevant registered plugins
