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>

environment: appfuse v2m4 + struts basic archetype

My appfuse application originally worked properly until I added the
following dependency to pom.xml:

    <dependencies>
        ......
        <dependency>
                <groupId>jasperreports</groupId>
                <artifactId>jasperreports</artifactId>
                <version>1.3.1</version>
        </dependency>
    </dependencies>

Once the above jasperreports dependency is added, executing "mvn
integration-test" failed with the following error messages:

[INFO] [talledLocalContainer] [myproject] ERROR [main]

I surfed the web and found out a related discussion at:
http://www.nabble.com/(no-subject)-t1718406.html
which says:
"You need to upgrade to the latest release of commons-collections.  Struts
Menu uses 3.0."

So, now my question is:
How to configure pom.xml to avoid the dependency conflict of
commons-collections so that I can use JasperReports?

Thanks in advance.
