Error: "No Persistence provider for EntityManager"

I have a project in Eclipse with an application that persists in the Postgresql 9.6 database through Hibernate, but Java is not recognizing the persistence-unit name that is set in persistence.xml , even this name by checking with the name passed to the "EntityManagerFactory" object.

Here is the exception log:

Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named bd2_persistence_unit
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:61)
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:39)
    at br.com.bd2.teste.TesteDatabase.main(TesteDatabase.java:15)

This is my main code:

package br.com.bd2.teste;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import javax.persistence.TypedQuery;

import br.com.bd2.exemplo.model.Fruteira;

public class TesteDatabase {
    public static void main(String[] args) {
        // Inicializacao da fabrica de objetos
        // persistenceUnitName = "bd2", ou seja, relaciona com a conexao na
        // persistence.xml (podera ter "n" unidades de persistencia)
        EntityManagerFactory emf = Persistence.createEntityManagerFactory("bd2_persistence_unit");
        EntityManager em = emf.createEntityManager();

        // Os comandos a seguir devem ser executados "um por vez"
        // Inserindo...
        em.getTransaction().begin();
        em.persist(new Fruteira("Fruteira"));
        em.persist(new Fruteira("Fruteira 3"));
        em.getTransaction().commit();

        // Atualizando...
        // Buscara a fruteira com id = 1. Observe o numero do id pelo pgAdmin3!
        Fruteira fruteira = em.find(Fruteira.class, 1L); 
        if (fruteira != null) {
            em.getTransaction().begin();
            fruteira.setNome("Fruteira Legal");
            em.merge(fruteira);
            em.getTransaction().commit();
        }
        // Recuperando "n" objetos...
        TypedQuery<Fruteira> q = em.createQuery("SELECT f " +
                                                "FROM Fruteira f", Fruteira.class);
        for (Fruteira each : q.getResultList()) {
            System.out.println(each.toString());
        }       

        // Excluindo...
        // Buscara a fruteira com id = 1. Observe o numero do id pelo pgAdmin3!
        fruteira = em.find(Fruteira.class, 1L); 
        if (fruteira != null) {
            em.getTransaction().begin();
            em.remove(fruteira);
            em.getTransaction().commit();
        }

        // Recuperando "n" objetos...
        q = em.createQuery("FROM Fruteira f", Fruteira.class);
        for (Fruteira each : q.getResultList()) {
            System.out.println(each.toString());
        }

        System.exit(0);
    }
}
