Right, Ant has no "parameter passing" to tasks, but it has "parameter
passing" to targets.
You could use for example
<target name="myEcho">
<echo message="${arg1}"/>
</target>
<target name="main">
<antcall target="myEcho">
<param name="arg1" value="message 1"/>
</antcall>
<antcall target="myEcho">
<param name="arg1" value="message 2"/>
</antcall>
</target>
and it should output "message 1" and "message 2".
Remaining problem is that there is no "nice" way to declare templates in ant
which can be used in every "sub-build". You must import a file containing
your generic target using the XML-way (using Entities).
