You know. I am really confused about the dependency stuff myself.
I am finding weird things happening, like moving the dependencies some where
else and back causes the problem again.
I looked at the output from mvn -X and noticed xerces 1.2.3 being referenced
by apache commons configuration. I put the following to get rid of the
error:
<dependency>
<groupId>commons-configuration</groupId>
<artifactId>commons-configuration</artifactId>
<version>1.4</version>
<exclusions>
<exclusion>
<groupId>xerces</groupId>
<artifactId>xerces</artifactId>
</exclusion>
</exclusions>
</dependency>
The dependency behavior is not consistent.

Abe
