You can't do that! Double interpolation doesn't work.
Fortunately, you can use a macro to accomplish it:
<macrodef name="ExpandPropertyValue"> <!-- evaluate nested
properties, ie ${${x}} work around -->
<attribute name="name"/>
<attribute name="value"/>
<sequential>
<property name="@{name}" value="${@{value}}"/>
</sequential>
</macrodef>

Hi,
Can someone let me know why the /${${env}.test} value not printed as
testest1/
*cmd*:ant -f build.xml -Denv=IT1
*build.xml*
<project name="Application Deployment" default="task" basedir=".">
<property file="build.properties"/>
<target name="task">
<echo>${env}</echo>
<echo>${${env}.test}</echo>
</target>
</project>
*build.properties*
IT1.test=testest1
*OUTPUT:*
task:
[echo] IT1
[echo] ${${env}.test}
BUILD SUCCESSFUL
