Accepted Answer

Instead of

```
Files.createDirectory(target, attr);
```

try using

```
Files.createDirectories(target, attr);
```

In the documentation for `Files.createDirectories()`:

Creates a directory by creating all nonexistent parent directories first. Unlike the createDirectory method, an exception is not thrown if the directory could not be created because it already exists.
