If you are using Homebrew and want to use the maven formular you have to delete the symbolic link /usr/bin/mvn.
Thereby you use your homebrew maven installation instead of the shipping version of OSX.
The executable is located at /usr/local/bin/ which should be part of your path already.
The maven package itself can be found at /usr/local/Cellar/maven/3.0.3/libexec. This will be interesting for your IDE, which often wants a pointer to your maven home directory. I created a symlink current so that I can change the version to use at the command line without the need to configure my IDE again.
[/usr/local/Cellar/maven] master@struggy$ sudo ln -s 3.0.3/libexec/ current
That’s it.
