Maven构建失败-找不到插件

我已经使用m2 eclipse工具创建了一个项目，并且现在选择了web应用程序原型。如果我尝试打包这个空的应用程序，我会得到一个构建失败

现在我已尝试更新存储库ect，但我没有运气

根据建议，我尝试更新插件注册表，但在我的文件系统中没有这样的文件pugin-registry.xml

---

此外，它在eclipse中构建得很好，但在命令中失败，所以我猜它们都使用不同的版本。如何修复此问题？

您缺少Maven构建正常运行所需的插件。检查并调整中的值，以便强制更新。您还可以使用命令行参数强制下载插件。

尝试使用

-cpu

标志。来自

mvn-帮助的输出

：

usage: mvn [options] [<goal(s)>] [<phase(s)>]

Options:
 -cpu,--check-plugin-updates            Force upToDate check for any
                                        relevant registered plugins

用法：mvn[选项][] 选项： -cpu，--check插件更新强制更新任何 相关注册插件

---

我遵循了以下步骤，它对我很有效。检查它是否对您有用

项目-->属性-->Maven-->用户设置

更改用户设置以指出以更正settings.xml

---

你的系统中应该有存储库文件夹。

这在我移回maven v 3.0.4时得到了解决。

谢谢，所以我尝试了这个方法。问题是我根本没有plugin-registry.xml文件。你能写完整的命令吗？因为我尝试了mvn-cpu，但它不起作用。@Msaleh maven 3没有cpu标志anymore@Msaleh使用它作为mvn后的一个标志，例如

mvn-cpu清洁安装
