We use p4 (perforce) as our source code control system, and p4 files are
read-only
unless checked out for editing. In this case, a file from our source tree gets
copied into the classes directory. If a "p4 sync" updates the the source file,
ant
will try to copy the updated file into the classes directory, but fail because
it is
read only. I would like a flag on copy that is the semantic equivalent of "cp
-f".
Overwrite seemed pretty close, but I'd be just as happy with "force". I'd
rather
not have to specifically delete the file, or change its file permissions.
