What exactly are you trying to achieve here? In your example, you
reference the name of the property you set the environment to....
<echo>${myprop.${env}.abc}</echo>
Why do you have the ".abc" there? I would think your goal would be
to define each "env" value as a property,eg.. abc=123, def=456, then
reference the property without naming it. Is that what you are
aiming for? How about...
ant -Denv=abc
<expand prop="myprop.${env}"/>
<macrodef name="expand">
<attribute name="prop"/>
<sequential>
<echo>[EMAIL PROTECTED]</echo>
</sequential>
</macrodef>
Output is: "123"
