Hibernate doesn't want to map the class in hibernate.cfg.xml

Question

I have a class User which is Entity. When I'm trying to map it in hibernate.cfg.xml

<mapping class="com.igorgorbunov3333.entities.User"/> 

get an error:

Exception in thread "main" org.hibernate.MappingException: Unknown entity: com.igorgorbunov3333.entities.User

But when I map class User programmatically It's work fine.

configuration.addAnnotatedClass(User.class);

What is the reason?

My Entity class:

package com.igorgorbunov3333.entities;

import javax.persistence.*;


/**
 * Created by Игорь on 01.07.2016.
 */

@Entity
@Table(name="user")
public class User {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;

    private String name;

    private String email;

    private String password;

    public int getId() {
        return id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

Try to use 4.3.6.Final version of hibernate. What hibernate version do you use? With 5.2.1.Final I saw the same problem. Solve by changing hibernate version.
