Problem with archetype properties

[Pablo Saavedra]

Hi All,

I'm using the archetype 2.0-alpha-1 plugin to create an archetype. Following
the guide, I added some requiered properties to the archetype-metadata.xml:

<requiredProperties>
   <requiredProperty key="projectName"/>
</requiredProperties>

But when I use the archetype, I'm not being prompted for the values, hence
they are not being replaced. Am I doing anything wrong?

Thanks in advance.
Pablo.
