Question

上周我将笔记本电脑更新到了Windows 10.从那时起，intelliJ就抛出了Maven相关的错误，我无法解决。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）的工件描述符。”。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克隆的项目，适用于其他所有人，所以问题不在于pom。

以下是我的Maven设置的屏幕截图：

我尝试过很多方法来解决这个问题，包括： 1.使高速缓存/重新启动无效 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清洁安装（稍后将触及此内容）。 6.做一个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。

以下是我尝试运行时控制台的错误输出：

最后，当我运行mvn clean -e以获取详细错误时，我收到以下错误：

Answer 1

Okey ...您遇到DNS问题...这意味着逻辑名称：repo.maven.apache.org无法转换为IP地址......这是您的操作系统和网络管理员的问题。 ..所以你的pom和intellij都很好......

更新：如果您有公司回购，则需要在.m2/settings.xml文件中添加公司回购...在Windows中，该文件夹位于用户系统文件夹中

我建议你使用最新版本的maven-compiler-plugin，目前是3.7.0。对不起，我没有其他问题的解决方案。

 <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>
