If you use Maven for builing Hibernate/Spring or JBoss Seam based projects and you refer to an external Maven2 repository like JBoss, you will sure run into the most hated feature of Maven2 — Transitive Dependencies.
Lets say you refer to Seam jars via an external pom, it not only gets Seam but also all the it’s non-optional dependencies which you don’t really require because you probably have them in your App, Server (In my case JBoss). Most of the apache commons jars, log4j, xerces and several other reusable jars are not really needed. Even worse, sometimes your app already has included it via another Jar and you don’t want to end up having multiple jars of same versions! With Transitive dependencies, this is exactly what happens. I use JBoss with ear deployement. So, when I directly used the pom structure for Seam, Richfaces, it stuffed in around 15 jars into my ear packaging which _I_dont_really_need. Luckily, there is a work around, ie., by adding “exclusions” in each of these dependencies. It’s a pain, I know but someone’s got to do it.
I’ve done job for you, so if you’re project is using the latest Seam, Hibernate, Richfaces on a JEE5 environment onJBoss 4.2.x and you need the right Maven 2 Repository pom structure with ear packaging, copy paste the following dependencies and customize it with your app. It should work like a charm. (I didn’t copy my entire pom as it has lot of other stuff in it)
Firstly, update your maven settings.xml to refer to JBoss Maven2 Repository. If you’re using JBoss Seam, rest assured, all your jars can be found in this exhaustive link. Even if you change versions in the near future, you’d not need to update the pom (except for the version property) as JBoss always refreshes the latest maven builds.
<profile> <id>your repo</id> <repositories> <repository> <id>jboss-maven2-repository</id> <name>JBoss Maven 2 Repository</name> <url>http://repository.jboss.com/maven2</url> </repository> </repositories> </profile>
Ear packaging is tricky, I hate it but JEE5 insists on ear even for simple webapps (someone please tell them!).
Michale Yuan did a great job of documenting the pom structure for ear deployement here. My structure is the same except that I ppint JBoss Repository to automatically download all jars.

I like externalizing versions as properties like in above as it’s easy to download latest ones periodically by just changing in one place Add this in each of the poms, for instance
<properties>
<seam.version>2.0.2.SP1</seam.version>
<richfaces.version>3.2.1.GA</richfaces.version>
</properties>
