Unfortunately Maven steps into the fray here. Maven will use the dependency
with the shortest path, so we have:
1) myproject -> appfuse-struts -> appfuse-web-common -> commons-collections
3.2
2) myproject -> jasperreports -> commons-collection old version.
As the path in two is shorter, it wins (you will see "closer found" in the
Maven logs) and the older version will appear in your app. The joys of
transitive dependencies! ;-)

That's strange you're getting this error - 2.0 M4 has an explicit
dependency on commons-collections 3.2 in the common-web project.
<!-- Fix for Maven thinking commons-collections-2.1 is newer than
3.1. -->
<dependency>
<groupId>commons-collections</groupId>
<artifactId>commons-collections</artifactId>
<version>${commons.collections.version }</version>
</dependency>
