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.mycom

Find out what process on your machine is holding the port. On Ubuntu Linux, I executed the following commands:

ps -ef | grep idea

Noticed that there is a Java process running the class org.jetbrains.idea.maven.server.RemoteMavenServer

I noted the pid of 2772 and executed

netstat -anp | grep 2772

I noted that pid 2772 was listening on port 6942

I telneted to that port:

telnet localhost 6942
Trying 127.0.0.1...  
Connected to localhost.
Escape character is '^]'.
/home/noahlz/.IdeaIC11/config/ home/noahlz/.IdeaIC11/system

So the Maven component used by IntelliJ runs as a distinct server process, which IntelliJ speaks to over a socket. You'll need to determine why IntelliJ can't reach that server port on your machine, i.e. what other process is holding onto that port and/or not sending a response back to IntelliJ

Note that the port number on your machine might be different.
