newbie: Cannot run "m2 install"

Hi Folks,

I´m trying get into maven and downloaded and installed maven 2 as
recommended. Now I´m in the "getting started" stage in understanding
maven. The create step for the default project worked fine but when I
try to run "m2 install" I get this stacktrace:

It looks as if it is being run in a directory without a project.

Try the archetype goal in the getting started guide.

Cheers,
