Maven home (M2_HOME) not being picked up by IntelliJ IDEA

Question

I am trying to do a simple maven build with IntelliJ IDEA 10.5.1 on OS X Lion and am getting the following error:

Error running my-app [package]: No

Answer 1

If M2_HOME is configured to point to the Maven home directory then:

1. Go to File -> Settings
2. Search for Maven
3. Select Runner

4. Insert in the field VM Options the following string:

   Dmaven.multiModuleProjectDirectory=$M2_HOME
   

Click Apply and OK
