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

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

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 valid Maven installation found. Either set the home directory in the configuration dialog or set the M2_HOME environment variable on your system.

I have set M2_HOME to the following, but I am still having issues. And yes, I did restart IntelliJ.

$ echo $M2_HOME
/usr/share/maven

I then manually entered the path to maven in IntelliJ's Maven Settings for the project. This is not something that I want to do for every project, so is there something I am missing with how to get IntelliJ know where my maven home is?

Solution

Mac OS apps cannot read bash environment variables. Look at this question Setting environment variables in OS X? to expose M2_HOME to all applications including IntelliJ. You do need to restart after doing this.
