----------------------------------------------------------
The cause appears to be the behaviour of FileUtils.prepareCopy(): if the source
is a directory, and the destination *doesn't* exist, then it will create the
required directory structure via a call to File.mkdirs(). The existence of the
destination directory is what causes symlink creation to fail.

> Key: IVY-1594
> URL: https://issues.apache.org/jira/browse/IVY-1594
> Project: Ivy
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.5.0-rc1
> Reporter: Simon Wade
> Priority: Major
>
> Creating symlinks to directories, during a retrieve, seems to _always_ fail
> on Windows 7, even when running with the required (elevated) privileges.
> Instead, the fallback copy method is always used.
> Running with verbose logging reveals the fallback is used due to a
> java.nio.file.FileAlreadyExistsException.
