I have used Indigo Java (not Java EE) and the maven plugin is already installed. Or at least, I know I have the possibility to import a Maven Project without installing anything.
But then I wanted to use Eclipse Indigo for Java EE developers. This version does not have maven already installed. I can not import a maven project. So I decided to install the m2e plugin.
And I have tried to install it many different ways (information on theses sites):

I also tried to use the Eclispe market place for the installation of the plugins. The installation process does not fail. But the Maven menu in import and Windows->Preference does not appear inside Indigo Java EE?
NB: I am running Windows 7, 64 bit edition
