本文介绍了无法将Maven项目导入IntelliJ IDEA的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在将任何Maven项目导入IntelliJ IDEA时遇到问题。我创建一个空的Maven项目，如下所示：
I'm having problems importing any Maven projects into IntelliJ IDEA. I create an empty Maven project like this:
$ mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
然后我尝试打开项目在IDEA（文件>打开项目，然后选择 pom.xml ）。一个表示阅读pom.xml的进度框显示几分钟，然后在没有打开项目的情况下消失。
Then I try to open the project in IDEA (File > Open Project, then choose the pom.xml). A progress box saying "Reading pom.xml" displays for a few minutes, and then just disappears without opening the project.
查看IDEA日志，我看到一些连接像这样的超时异常：
Looking in the IDEA log, I see some connection timeout exceptions like this:

我使用的是最新版本的IDEA（11.1.3）和Maven（3.0.4）。任何想法我做错了什么？
I'm using the latest versions of IDEA (11.1.3) and Maven (3.0.4). Any ideas what I am doing wrong?
推荐答案
这是与网络和地址解析相关的常见问题。在某些情况下， localhost 可能无法解决，并且需要
It's a common problem related to networking and address resolution. In some cases localhost may not resolve and it's required to have
127.0.0.1 localhost
in / etc / hosts 文件。还要确保没有其他IP地址映射到 localhost 。
in /etc/hosts file. Also make sure there are no other IP addresses mapped to localhost.
以获取更多详细信息。
See my comment in the related YouTrack issue for more details.
