You could try playing with beanshelldef http://marc.theaimsgroup.com/?l=ant-dev&m=106577547220771&w=2

Hi,
my current struggle with <script/> and beanshell, made me notice how inefficient or script task is (i.e., on every execution the script is recompiled, and executed).
Although there is no other way for <script/> it would be nice is <scriptdef/> could do something more efficient. Currently <scriptdef/> will recompile the src on every invocation of the defined script.
It would be nice if we could somehow cache the already parsed source, and being able to reexecute it multiple times with different element and attribute instances on each execution. So, to treat it a little more like compiled code.
The way I see it, such a script definition would specify an expression entrypoint that can be called over and over. Something like:
<scripdef name="myscript" language="beanshell" execute="executeScript()"> <attribute name="att1"/> void executeScript() { print (attributes.get("att1")); } </scriptdef>
The execute attribute indicates the expression to be evaluated on each <myscript/> instance, and it also indicates that it is safe to keep the compiled source (i.e., bsf engine object around).
Notice that it may not be thread-safe to do this since the engine is statefull. hummmm
So, what do people think?
