Files.move REPLACE_EXISTING cannot be resolved by a variable

Question

The documentation Files.move(Path source, Path target, CopyOption... options)says:

As an alternative, suppose we want to move the file to a new directory, keeping the same file name and replacing any existing file with this name in the directory:

 Path source = ...
 Path newdir = ...
 Files.move(source, newdir.resolve(source.getFileName()), REPLACE_EXISTING);

Why am I getting an error in the following code?

 Files.move(Paths.get("outputFilePath"), Paths.get("inputFilePath"), REPLACE_EXISTING);
