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

I can't remember the specific reasons why that won't expand...but I've had
that issue in the past. What I've done is to create a deref macrodef for
that purpose. Here is a fix (not sure its what you want):
<project name="Application Deployment" default="task" basedir=".">
<macrodef name="deref">
<attribute name="property"/>
<attribute name="value"/>
<sequential>
<property name="@{property}" value="${@{value}}"/>
</sequential>
</macrodef>
<property file="build.properties"/>
<target name="task">
<echo>${env}</echo>
<deref property="myProperty" value="${env}.test"/>
<echo>${myProperty}</echo>
</target>
</project>
When I run using the same build.properties, I get this:
> ant -Denv=IT1
task:
[echo] IT1
[echo] testest1
BUILD SUCCESSFUL
