Hi
use the if/unless attribute of <target> so you can create two targets where
one is accessed if the property is set and the other is accessed if the
property is not set. Like the following hack
<project name="Hugo" default="param_available" basedir=".">
<target name="param_available" if="param" depends="param_notavailable">
<echo message="param set value=${param}"/>
</target>
<target name="param_notavailable" unless="param">
<echo message="param notset"/>
</target>
</project>
This xml syntax should make the following output
if param is set -> param set value= xxx
and if not -> param is not set
Yours
