This will exclude jaxen from the dependency:
<dependency org="org.jdom" name="jdom" rev="2.0.2">
<exclude module="jaxen"/>
</dependency>
This will exclude cobertura and findbugs
<dependency org="org.jdom" name="jdom" rev="2.0.2">
<exclude name="maven-cobertura-plugin" />
<exclude name="maven-findbugs-plugin" />
</dependency>
