intelliJ中的Maven无法读取工件描述符-启用快照更新

Question

上周，我的笔记本电脑更新到Windows 10。从那时起，intelliJ抛出了与Maven相关的错误，我一直无法解决。我所有的Maven插件都以红色突出显示，错误为：“未能读取（依赖）的工件描述符。”。这发生在每个插件和依赖项上。我还应该提到这是一个克隆项目，适用于其他所有人，所以问题不在于pom。

我已经尝试了很多方法来解决这个问题，包括：1。使缓存无效/重新启动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.正在进行Maven clean安装（稍后将对此进行讨论）。6、进行git拉取并重新导入。安装外部Maven（最新版本），将其添加到环境变量和intelliJ中。

以下是我尝试运行时控制台的错误输出：

关于下面的警告

[WARNING] Some problems were encountered while building the effective
model for (redacted)

compiler-plugin is missing. @ line 78, column 21 [WARNING]  [WARNING] It is 
highly recommended to fix these problems because they threaten the stability

[WARNING] For this reason, future Maven versions might no longer support

我想建议您使用目前3.7.0的最新版本的maven-compiler-plugin。对不起，我没有解决其余问题的方法。

 <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.7.0</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
  </plugin>

好吧。。。你有DNS问题。。。这意味着逻辑名称：repo。专家阿帕奇。无法将组织转换为IP地址。。。这是您的操作系统和网络管理员的问题。。。所以你的pom和intellij很好。。。

更新：如果您有公司回购，则需要在您的中添加公司回购。平方米/设置。xml文件。。。在windows中，该文件夹位于用户系统文件夹中
