DirectoryScanner: getExcludedFiles performance issue using ant fileset

Question

Is there a way to speed up the performance of getExcludedFiles()? I've been play around with the fileset patterns, but could not get any improvement.

Here is my situation:

I have a fileset defined with these patterns:

basedir/normal/abc/control/*.ins
basedir/normal/abc/models/bx/cells/*.l

under basedir/normal, there are about hundred other subdirectories, but I am only interested in the abc. However, when I am calling the DirectoryScanner.getExcludedFiles(), I think it called slowScanner() and apparently it must have scanned all the other subdirectories, which led to a 24 hours turnaround. Any help would be greatly appreciated.

Thanks in advance,

You should set the dir of The file set to basedir/normal/abc then your patterns will be:

control/*.ins
models/bx/cells/*.l
