Unable to import maven project in IntelliJ14

Question

I'm trying to import the Maven projects from IntelliJ button (the one with the arrows in circle), but I get the following message "Unable to import maven project. See logs for details", as shown in the following picture

If I go into the log, I see:

I'm using Maven 3.3.3 and JDK 1.7.0_71 on a 64bit Ubuntu machine.

Strange thing, is that I can use Maven by command line. Any idea?

In my case I'd just upgraded my OS (OSX) and doing so deleted my JDK, so Intellij was quietly failing. Following @JeanValjean's advice meant that the project was no longer loadable at all (I couldn't get to JVM preferences). Looking in ~/Library/Logs/IntelliJIdeaXX/idea.log told me the problem and deleting ~/Library/Caches/IntelliJIdeaXX and ~/Library/Preferences/IntelliJIdeaXX/options/jdk.table.xml let me open the project again and fix the path to the JDK.
