RE: How to a act based on property value, _not_ if set [was: ANT copy on condition]

[Ja...@rzf.fin-nrw.de]

<!-- which to use -->
<input addproperty="which" validargs="One,Two,Default"/>

<!-- that´s the trick -->
<antcall target="do${which}"/>

<target name="doOne"/>
<target name="doTwo"/>
<target name="doDefault"/>
