maven-archetype-quickstart creating incorrect tree structure

Newbie to Maven here, so apologies if this is a simple one.

I'm trying to create a standard directory layout using archetypes, however selecting archetype 15 (quickstart) as suggested here creates a tree structure with src/main, src/site instead of src/test. Any idea what I'm doing wrong here?

Maven version is 3.0.3, no idea how to tell what version of the archetype plugin I'm using.
