Once an Ant property is set, you can't change it. However, there are a
few ways to get around this:
1). In an antcall, you set <param> and these parameters are inherited
as properties in the called target:
<target name="first">
<antcall target="subtask">
<param name="param1" value="${JAVA_HOME}"/>
</antcall>
</target>
<target name="second">
<antcall target="subtask">
<param name="param1" value="d:/install"/>
</antcall>
</target>
<target name="default"
depends="first,second"/>
<target name="subtask">
<echo message="Param1 is now set to ${param1}"/>
</target>
2). You can do something similar with macrodef
3). Use AntContrib's <var> task:
http://ant-contrib.sourceforge.net/tasks/tasks/variable_task.html.
Running "ant default" will print out two different values for ${param1}.
