Andrew Shcheglov commented on IO-719:
-------------------------------------
Possible solution: stringize relative path inside"resolve()" in
"CopyDirectoryVizitor.preVizitDirectory()" and
"CopyDirectoryVizitor.vizitFile()", like here:
{code:java}
@Override
public FileVisitResult preVisitDirectory(final Path directory, final
BasicFileAttributes attributes)
throws IOException {
final Path newTargetDir =
targetDirectory.resolve(sourceDirectory.relativize(directory).toString());
if (Files.notExists(newTargetDir)) {
Files.createDirectory(newTargetDir);
}
return super.preVisitDirectory(directory, attributes);
}
@Override
public FileVisitResult visitFile(final Path sourceFile, final
BasicFileAttributes attributes) throws IOException {
final Path targetFile =
targetDirectory.resolve(sourceDirectory.relativize(sourceFile).toString());
copy(sourceFile, targetFile);
return super.visitFile(targetFile, attributes);
}
{code}
> PathUtils.copyDirectory() does not work when source and dest belong to
> different filesystems
