You can do this in Ant 1.7.1 without any extensions:
<property id="value.3" value="3"/>
<property id="value.4" value="4"/>
<property name="id" value="3"/>
<property name="value.id" refid="value.${id}"/>
<echo>${value.id}</echo>
I use this to set up builds for different platforms. For example,
<property id="cc.flags.arm" value="..."/>
<property id="cc.flags.x86" value="..."/>
<property id="cc.flags.mips" value="..."/>
<property name="cc.flags" refid="cc.flags.${arch}"/>

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!!
