groovy - how do i create derived required properties for maven archetypes during generation -

i need provide derivative custom required properties during archetype:generation when using archetype. maven supports custom required properties derive buit-in properties artifactid , rootartifactid. due long-standing evaluation ordering issues, not possible reliably derive custom properties.

i found solution might work, using groovy maven plug-in here.

the problem proposed solution initialization phase not apply non-pom uses archetype generation. question how can use groovy maven plugin during archetype:generate? cannot seem invoked. cannot figure out phase value use.
