I was reading these different articles on how to install Maven on Mac OSX and I had to create the /usr/local directory, check the md5sum, untar and then modify my profile.
All this to realize that Maven is already installed on my Mac by default. It is version 2.2.0 and not the latest 2.2.1 but for the book I am reading this is perfect.
A little bit of testing before starting to do all sort of crazy things would have simplified my life.
I installed the m2eclipse plugin in my Eclipse so I can get ready to see how it simplifies my life by not having to write the pom.xml.
