For example, let's say that you want to have a *path operation* that allows to update items, and returns HTTP status codes of 200 "OK" when successful.

But you also want it to accept new items. And when the items didn't exist before, it creates them, and returns an HTTP status code of 201 "Created".

To achieve that, import `JSONResponse`, and return your content there directly, setting the `status_code` that you want:

            )
            .map(sourceSet -> sourceSet.getOutput().getClassesDirs())
            .reduce(FileCollection::plus)
            .orElse(getProject().files())
            .filter(File::exists);
    }
