createSymbolicLinkOrCopy
```
public static boolean createSymbolicLinkOrCopy(java.io.File link,
                                               java.io.File target)
```
Creates a symbolic link from link to the target, or copies target to link if running on Windows.
Creating symbolic links on Windows requires administrator permissions, so copying is a safer fallback. Copy only happens if timestamp and and file length are different than target

Parameters:

link - the location of the symbolic link, or destination of the copy.

target - the source of the symbolic link, or source of the copy.

Returns:

true if the operation succeeds, false otherwise.

public static boolean createSymbolicLinkOrCopy(java.nio.file.Path link,

```
Creates a symbolic link from link to the target, or copies target to link if running on Windows.
Creating symbolic links on Windows requires administrator permissions, so copying is a safer fallback. Copy only happens if timestamp and and file length are different than target

Parameters:

link - the location of the symbolic link, or destination of the copy.

target - the source of the symbolic link, or source of the copy.

Returns:
