I have a problem using maven: at the beginning I ran maven 2.0.9 and I specified nothing to the variable M2_REPO.
so I created a test application with the command :

mvn archetype:create -DgroupId=testapp -DartifactId=testapp

and there were no '.m2' directory created in usual places (/home, /home/lolveley, /home/lolveley/Documents).

now I do not know where the repository is and if I launch the previous command (mvn archetype...) there are not downloads made and I suppose maven to find somewhere in the disk the files(in the repository?).

my question is simple: how can I find the path of the repository?(I need it in order to use androMDA.)
or maybe how to change the path of the repository?
