> If we pass `-yt ` a symbolic directory, we will get an exception:
> {code:java}

> The root cause is not here but in :
> {code:java}
> final java.nio.file.Path shipPath = file.toPath();
> final java.nio.file.Path parentPath = shipPath.getParent();
> Files.walkFileTree(
> shipPath.toRealPath(),
> new SimpleFileVisitor<java.nio.file.Path>() {
> @Override
> public FileVisitResult visitFile(
> java.nio.file.Path file, BasicFileAttributes attrs) {
> localPaths.add(new Path(file.toUri())); //root cause:
> localPath is an symbolic file, without any file under real path.
> relativePaths.add(
> new Path(
> localResourcesDirectory,
> parentPath.relativize(file).toString()));
> return FileVisitResult.CONTINUE;
> }
> });
> {code}
