Feature request has been made <http://jira.jboss.com/jira/browse/JBSEAM-225>.
The pom.xml presented here is missing dependencies to 3rd party jar and it's merging the jboss-seam-ui.jar to jboss-seam.jar.
There will be needed a super pom for jboss-seam project itself and separate poms for both of the jars if current build process is to be followed. Also the maven naming convention is not followed in groupId (suggesting org.jboss.seam). I'd appreciate SNAPSHOT version numbering in cvs trunk and "real" numbers in different branches.
Maven people have made an excellent tutorial about all this <http://www.mergere.com/m2book_download.jsp>
