Unable to make a Persistence provider for EntityManager connection (Glassfish / Mysql / Maven)

Question

I'm new to Java EE 7. And I'm now stuck with making a Persistence connection.

It turned out that the error I'm running is common. I have tried the suggested solutions. But apparently I'm still doing something wrong. Hopefully someone will see the mistake I made.

Glassfish 4.1, Maven, Mysql 5.1.44 and I use Netbeans 8.2.

When I run the Test class. I get the following Exception:

Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named Test6_MYSQL
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:61)
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:39)
    at com.mycompany.simpleform5.Test.main(Test.java:25)

I have tried different solutions suggested in:

I have implemented the instructions explained in: No Persistence provider for EntityManager named --> I’ve changed the "hibernate-entitymanager.jar" for a newer version: "hibernate-core.jar".

I have also tried other the older Persistence versions 1.0 and 2.0.

I have changed the org.hibernate.ejb.HibernatePersistence: (https://stackoverflow.com/a/1285436/784594).

I used the hibernate-core-5.2.2.Final.jar (Hibernate 5.2.2: No Persistence provider for EntityManager). But that didn't work.

The java class:

public class Test 
{
    public static void main (String[] args)
    {
        [..]
        EntityManagerFactory emf = Persistence.createEntityManagerFactory("Test6_MYSQL");
        EntityManager em = emf.createEntityManager();
        [..]

    }

}
