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?
