i would let the upper hierarchy be the arbiter e.g.
//assume some property classes.dir which will be changed depending on os
<project name="master">
<target name="choose-classes-dir">
<property name="classes.dir" value="non_sparc_classes" />
<condition property="classes.dir">
<os name="SunOS" arch="sparc" value="sparc_classes/>
</condition>
<ant antfile="subproject/property_based_subbuild.xml" name="jarit"
inheritrefs="true">
<property name="classes.dir" value="${classes.dir}"/>
</ant>
</target><project name="subproject/property_based_subbuild.xml">
<target name="jarit">
<jar destfile="jar1.jar">
<fileset refid="reqdClasses"/>
</jar>
<classfileset id="reqdClasses" dir="${classes.dir}">
<rootfileset dir="${classes.dir}"
includes="org/apache/tools/ant/Project*.class"/>
</classfileset>
</target>
</project>
closest i can come without going to maven
