How to resolve directories given in an ant pattern?

[Ognjen Bubalo]

Hi,

I am using build.getEnvironment(listener).expand(input) to resolve files 
given in ant pattern. How can I do the same just to resolve directories? I 
get a list of FilePaths and I tried to iterate through it while checking 
isDirectory(), but did not help.

How can I do this?

Thanks,
Ogi
