Maven 3.3.1 ECLIPSE: -Dmaven.multiModuleProjectDirectory system propery is not set

I just installed Maven 3.3.1 on Mac OS X, and building a Maven Project with Eclipse is giving me this error:

-Dmaven.multiModuleProjectDirectory system property is not set.
Check $M2_HOME environment variable and mvn script match.

It did not happen before with Maven 3.2.5.

Is there any way to fix this (except downgrading to 3.2.5) ?

Where exactly can I set this "multiModuleProjectDirectory" property in Eclipse?

In Eclipse you need to go like this.

Window-> Preference -> Java -> Installed JREs -> Edit

In the edit Default VM arguments you need to put

If you already set the maven home.

-Dmaven.multiModuleProjectDirectory=$M2_HOME

In IntelliJ you can set this option in VM Options field that you can find in the next configuration view:

Preferences/Build, execution, deployment/Build tools/Maven/Runner

This was filed as a bug with m2e in Eclipse at https://bugs.eclipse.org/bugs/show_bug.cgi?id=462944 , due to the changes in Maven 3.3.1.

This is fixed in m2e 1.5.2 as of 2015-04-13. This is an available release that can be installed from http://download.eclipse.org/technology/m2e/releases/ .

(No more changing JVM arguments for the entire workspace or for specific launch configurations required.)

Define like this in the JVM options:

-Dmaven.multiModuleProjectDirectory=HOME_PATH_OF_YOU_PROJECT

In case you have this error message on your commandline, please verify if your PATH variable points to the same maven installation apache-maven-3.X.X/bin folder as your M2_HOME variable. In my case I was mixing up two versions which resulted in this error.
