Good afternoon,
I recently noticed a issue when we update our projects from Commons-io
2.11.0 to 2.13.0 with FileUtils.copyFile
In our code base, we was using FileUtils.copyFile(src, dst) , that as is
said on the JavaDoc, must preserve the file's last modified date/times.
Sometimes, we do this over a SMB/CIFs share folder, and we never had
problems or errors with this.
But, since we update to 2.13.0 , we got IOExceptions because copyFile
fails to preserve the file's last modified date/times. I see that the
implementation changed a bit. on 2.11.0 copyFile uses directly
File.setLastModified(long) and now tries with
BasicFileAttributeView.setTimes(FileTime, FileTime, FileTime) and if
fails, tries with File.setLastModified(long) . So, it should keep
working exactly like before. But, obviously, for our use case, isn't. We
workaround , calling copyFile with preserveFileDate set to false.
Also, I noticed an problem with the actual API of FileUtils.copyFile
methods. I think that an improvement should be that when copyFile fails
to set file's last modified date/times, should throw a different
exception from IOException (extend an exception from it). Actually it's
imposible to differentiated from another bigger IO problems. In out
case, we would like to try to preserve the file's last modified
date/times, but ignore the error if it fails to do that. And I can't see
any way of doing it. Specially with the current implementation of
FileUtils.copyFile .
