You could file a defect with ant's bugzilla, but I think it'd be filed
as invalid

1. <copy> compares dest to source timestamps, and unless you say
'preservelastmodified=true' timestamps the dest to the copy time.

2. so all following copies wont work as the dest file is newer than
the source(s), unless you actually edit the source.

3. You can use the <different> selector in your fileset to compare
files for byte-for-byte difference; this is actually very fast if the
file sizes differ.

Any build process that overwrites files in the source tree is
inherently hazardous. Better perhaps to copy to an intermediate dir
and building from there.
