Subject Mapping files into a JAR, seemingly impossible.
Date Mon, 29 Jul 2002 15:41:23 GMT

	I have a task that I need to do that I can't quite nail down. I am 
beginning to wonder if there is an easy way to do it in Ant at all, outside 
of exec'ing some 5 line perl script....
	I want to essentially write something like this:

<jar update="${update_val}"
         destfile="${}/resources.${environment}.jar" >
	<mapper type="glob"  from="*.${environment}" to="*"/>
	Of course, the jar task doesn't support mappers as a nested parameter so ....

	The logic behind what I want to do is pretty simple: create a jar that 
contains files that are stripped of their ${environment} trailing ...

	An example: Say I have a directory 
ROOT/WEB-INF/conf/  I want to create a JAR that 
has _only_ this file, renamed as 
ROOT/WEB-INF/conf/    - that's it!

Thanks for any input. The only other route I considered going was copying 
files with the mapper, then adding those to the JAR but I don't see a way 
to create a FileSet for the JAR out of the mapping set.

I don't know .. am I missing something here?

Thanks in Advance,
Jeremy Kuhnash
