Re: Jar Target

Hi Chris,
the first possibility to do that is as Vita correctly has guessed -- 
setup a filter each time manually by enumerating all files of the 
implementation and all files of the interface. This would probably have 
to be done upon each compilation , as the set of input files changes.

If there was some naming pattern, you could filter the files by a 
regular expression . That's simple though I won't go deeper for now, as 
I expect that it's not the case.

The most correct and robust solution , is to define the filter 
declaratively by using an implementation of JarContent.NameFilter that 
would pass / not-pass files based on the contents of the sources container.
JarContent.NameFilter which has just one method   *boolean 
contains(String) *
The meaning is obvious , I guess.

Such a filter is not readily implemented of course, as I couldn't have 
expected this requirement. But implementing it is a piece of cake. I can 
do it for you.

P.S. I'm back to jarpackager
