Multi Module Project Setup: When not to use?

[Jojo Paderes]

Hi,

I'd like to know your thoughts on when not to use a multi module project
setup.

For example for a typical 3-tier web application
(ui+controllers/service/data-access), will a maven-archetype-webapp suffice
for this setup, or would a multi-module project setup be more pragmatic?

Thanks!
