Re: Howto declare a dependency on a group of modules

[Wayne Fay <wa...@gmail.com>]

I think you're looking for something like this...

EJB Client projects
ejb1 - pom.xml
ejb2 - pom.xml
ejb3 - pom.xml

application-x-ejb-client - pom.xml
<dep>ejb1</dep>
<dep>ejb2</dep>
<dep>ejb3</dep>

app1 - pom.xml
<dep>application-x-ejb-client</dep>

When starting a new project (app1 above), you only need to declare a
single dependency on application-x-ejb-client project, which will
transitively pull in the ejb1, ejb2, and ejb3 dependencies.

Give this a try and stay flexible to try some other approaches as you
become more comfortable with Maven and fully integrate it into your
development process.
