I have a similar configuration in my project.
It is an EAR project with lots of WARs on their own. The goal was to provide a
way to be able to debug/develop the WARs standalone e.g. via mvn tomcat7:run.
In this situation you need all your dependencies (even platform JARs like
openwebbeans, myfaces and openjpa) in your WEB-INF/lib folder. But those libs
should not get packaged when building the final EAR.
I ended up with an own 'ear' profile with has war-excludes set:
<profiles>
<profile>
<id>ear</id>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<packagingExcludes>
${war.excludes}
</packagingExcludes>
the war.excludes properties is maintained in a central location. Please note
that the war.excludes contains a list of file names and not packages.
E.g. WEB-INF/lib/openwebbeans-*,WEB-INF/lib/myfaces-api-*, ...
