Hi,
Just curious. If each java file in a project is specified as an entry in
include pattern what would be the performance impact and when it would be
observed the most?
All the best.

Philippe,
That is what I was guessing. Thanks for your confirmation.
I am writing an adapter for a legacy project format that explicitely
specifies each file in a project. Legacy format does not map to filesystem
one-to-one. For example, there might be extra source files on the
filesystem in the same directory where specified sources are and so on.
Have to write a clever algorithm that computes inclusion/exclusion rules :)
Cheers.
