java - intelliJ 中的 Maven 无法读取 Artifact 描述符 - 启用快照更新

Question

上周我的笔记本电脑更新到了 Windows 10。从那时起，intelliJ 抛出了 Maven 相关的错误，我一直无法解决这些错误。我的所有 Maven 插件都以红色突出显示，并显示错误:“无法读取(依赖项)的 Artifact 描述符。”。每个插件和依赖项都会发生这种情况。我还应该提到这是一个适用于其他所有人的克隆项目，因此问题不在于 pom。

这是我的 Maven 设置的屏幕截图:

我尝试了很多选项来解决此问题，包括: 1. 使缓存失效/重启 2.重新导入项目 3.重新导入Maven依赖项。 4.删除intelliJ.iml和.idea文件夹。 5. 进行 Maven 全新安装(稍后会谈到这一点)。 6. 执行 git pull 并重新导入。 7.安装外部Maven(最新版本)，将其添加到环境变量和intelliJ中。

下面是我尝试运行时控制台的错误输出:

最后，当我运行 mvn clean -e 查看详细错误时，我收到以下错误:

好吧...您遇到了 DNS 问题...这意味着逻辑名称:repo.maven.apache.org 无法转换为 IP 地址...这是一个问题你的操作系统和网络管理员...所以你的pom和intellij没问题...

更新: 如果您有公司存储库，则需要在 .m2/settings.xml 文件中添加公司存储库...在 Windows 中，该文件夹位于您的用户系统文件夹
