Java 找到非托管pom.xml文件（无法在IntelliJ中导入maven项目）

我无法在IntelliJ中导入我的maven项目。该项目具有pom.xml文件，但IntelliJ不会加载该文件。检查以下日志：

Caused by: java.lang.RuntimeException: Cannot reconnect
Caused by: java.rmi.RemoteException: Cannot start maven service; nested exception is: 
    java.rmi.ConnectException: Connection refused to host: localhost; nested exception is: 
    java.net.ConnectException: Operation timed out (Connection timed out)
Caused by: java.rmi.ConnectException: Connection refused to host: localhost; nested exception is: 
    java.net.ConnectException: Operation timed out (Connection timed out)
Caused by: java.net.ConnectException: Operation timed out (Connection timed out)

我在etc/hosts中只保留了下面的块，这很有效：

127.0.0.1 localhost

看，这是关于记忆的。我想我的问题是关于网络，但是谢谢你的建议！看见
