Subject: using dynamic declarations..
/*
Hi,
I was wondering if it is possible to use 'dynamic declarations' within ANT.
Please check the example below. In the line '<echo>${value.${id}}</echo>', I
would like to print a value which is dependant on the id. But for now, I
cannot use this construction, because it prints '${value.${id}}' literaly.
If possible, how can I still use this construction?
I hope someone can help. Thanks!!

<target name="check.numberr">
<var name="value.3" value="3" />
<var name="value.4" value="4" />
<var name="id" value="3" /> <!-- now it is 3, but it can also be 4
-->
<echo>${value.${id}}</echo> <!-- how to use this? -->
<echo>${value.3}</echo> <!-- this works -->
</target>
*/
a solution with AntXtras (http://jwaresoftware.org/wiki/antxtras/home) =
<!-- import AntXtras -->
<taskdef resource="org/jwaresoftware/antxtras/antlib.xml"/>
<!-- enable funcuts -->
<managefuncuts action="enable"/>
<target name="main">
<assign var="value.3" value="foobar"/>
<assign var="value.4" value="foobaz" />
<!-- now it is 3, but it can also be 4 -->
<assign var="id" value="3" />
<echo>Should print 'foobar' => ${$var:value.${$var:id}}</echo>
<echo>Should print 'foobaz' => ${$var:value.4}</echo>
</target>
will print =
main:
[echo] Should print 'foobar' => foobar
[echo] Should print 'foobaz' => foobaz
BUILD SUCCESSFUL
