Subject Re: Uptodate working one way only
Date Tue, 12 Aug 2008 16:15:57 GMT
Well, copy works great - it only copies files that changed.

But in IF the files changed, I need to go to the place where all the
java files are and delete ALL the java files. Because I really don't
know what files will be generated, and as long as I don't copy new idl
files it is okay to leave them, but as soon as a new idl is copied
over (or a changed one) ... that is where I need to re-generate all
the java again.
