Can I alter packaging with Maven?

Hi,

I'm a fairly basic maven user and would like to know if it is possible to
have maven support multiple type of packaging or if I need to look at a
different mechanism.

What I want to do is to build a JavaFX application that depending on how it
is packaged is either a desktop app or a web app.

There would potentially be some different configuration files that would
pertain to the different packaging options.

Can I use maven in this way or does someone know of another means of
accomplishing the same thing?

Thanks.

Les
