现在我尝试更新存储库等，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。

它也在eclipse中构建得很好但是从命令失败，所以我猜它们都使用不同的版本。如何解决这个问题？

Answer 1

尝试使用-cpu标志。 mvn -help的输出：

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

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

Answer 2

您缺少Maven构建功能所需的插件。检查并调整Plugin Registry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。

Answer 3

我按照以下步骤操作，它对我有用。检查它是否对您有用。

项目 - ＆gt;属性 - ＆gt; Maven - ＆gt;用户设置

更改用户设置以指出更正settings.xml 您的系统中应该存在您的存储库文件夹。

Answer 4

当我回到maven v 3.0.4时解决了这个问题。

Maven构建失败 - 无法找到插件
