メソッドのクエリーメタモデルを作成できませんでした。public abstract java.util.Optional

ライブラリのバージョンに苦しんだ後、私は固執しています。 A similar questionは、3歳で、私は多くの新しいバージョンのものを使用しており、Optional<>について不平を言っているので、適用されていないようです。私のGradleファイル：https://github.com/JetForMe/spring-hoa/blob/master/build.gradle?ts=4 メソッドのクエリーメタモデルを作成できませんでした。public abstract java.util.Optional

public 
interface 
UserRepository 
    extends JpaRepository<User, Long> 
{ 
    Optional<User>    findByLogin(String inLogin); 
}

エンティティ

@Entity public class User 
{ 
    public 
    User(String inLogin, String inClearPassword) 
    { 
     mLogin = inLogin; 
     mEncryptedPassword = inClearPassword;  // TODO 
    } 

    public Long   getId()      { return mId; } 
    public String   getLogin()     { return mLogin; } 

    @Id 
    @GeneratedValue 
    private Long     mId; 

    @JsonIgnore 
    public String     mEncryptedPassword; 
    public String     mLogin; 
}
