Implementação com mais de uma palavra

Verifiquei alguns exemplos de outros tópicos comentando formas de resolver a questão de que o scanner não aceita espaços vazios.

Tentei aplicar o delimitador "\n", mas o meu sistema não está aceitando.

O que pode estar acontecendo?

Código:

    private void salvar(Scanner scanner) {
        scanner.useDelimiter("\n");
        System.out.println("Descricao do Cargo");
        String descricao = scanner.next();
        Cargo cargo = new Cargo();
        cargo.setDescricao(descricao);
        cargoRepository.save(cargo);
        System.out.println("Salvo");
    }

Exception:
