You could also use beanshell. Not sure if this works due to a bug or feature.
We use it very sparingly in our build process (analagous to like goto in C).
<?xml version="1.0" encoding="utf-8"?>
<project name="ant_dev_problem" default="build">
<scriptdef name="beanSetProperty" language="beanshell">
<!-- setProperty appears *not* to respect Ant's property,
immutability. Appears to be a change in 1.7.0.
Note that setNewProperty *does* respect immutability -->
<attribute name="name"/>
<attribute name="value"/>
<![CDATA[
String n = attributes.get("name");
String v = attributes.get("value");
project.setProperty(n, v);
]]>
</scriptdef>
<macrodef name="a">
<attribute name="module"/>
<sequential>
<beanSetProperty name="myvalue" value="@{module}" />
<echo>inside macro: ${myvalue}</echo>
</sequential>
</macrodef>
<target name="build">
<a module="venus"/>
<echo>outside macro: ${myvalue}</echo>
<a module="mars"/>
<echo>outside macro: ${myvalue}</echo>
</target>
</project>
$ ant -q
[echo] inside macro: venus
[echo] outside macro: venus
[echo] inside macro: mars
[echo] outside macro: mars
BUILD SUCCESSFUL
Total time: 0 seconds
Hope this helps.

Subject: Having problem using property to in macrodef if invoke for more than
one time
Hi,
I love the macrodef task. However, it has a weakness. We must be very
careful if using property within the macrodef. I face problem with a
macrodef that is more complicated than the following example. I have
to use dirname and condition in my macrodef, but it cause problem if I
invoke macrodef for more than one time as the property has been set
for the first time. Here is an example that trying to replay the
situation I face:
<macrodef name="a">
<attribute name="module"/>
<sequential>
<property name="myvalue" value="@{module}"/>
<echo>${myvalue}</echo>
</sequential>
</macrodef>
<target name="build">
<a module="venus"/>
<a module="mars"/>
</target>
I expect the output should be
[echo] venus
[echo] mars
but it turn out:
[echo] venus
[echo] venus
I think this is a common issue using macrodef and there are some
temporary solution to pass a temporary property name to the macrodef.
This is not feasible in my situation as I need to pass more than 5 to
10 properties to my macrodef.
Some other solution is using local property but I couldn't find this
task. I am using ANT 1.7.0.
Any solution? Please advice. Thank you very much.
