Unable to import Maven project into IntelliJ IDEA

Question

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 

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.

Looking in the IDEA log, I see some connection timeout exceptions like this:

I'm using the latest versions of IDEA (11.1.3) and Maven (3.0.4). Any ideas what I am doing wrong?

Answer 1

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 file. Also make sure there are no other IP addresses mapped to localhost.

See my comment in the related YouTrack issue for more details.
