you need to specify a the mapper for srcfiles and specify the type for mapper
<property name="xmlBuild.notRequired" location="dest"/>
<uptodate property="xmlBuild.notRequired">
<srcfiles dir="${src}/xml" includes="**/*.dtd"/>
<mapper type="merge" to="${dest.dir}/xmlBuild.notRequired"/>
<targetfile="${deploy}\xmlClasses.jar"
</uptodate>
http://ant.apache.org/manual/CoreTasks/uptodate.html
merge type means The target file name will always be the same, as defined by
to - from will be ignored.
