Could not locate cfg.xml resource with hibernate.5.2.2.Final + spring.4.0.6.RELEASE in IDEA 2018.1

I upgraded my Idea from 2017.1 to 2018.1 and I have a Hibernate issue I can't solve... I've searched and it seems there are many problems with this but couldn't figure out what's the solution.

So, I'm using hibernate.version 5.2.2.Final, spring.version 4.0.6.RELEASE, my hibernate.cfg.xml is in src\main\resources folder and in my HibernateUtils I had something like this:

public class HibernateUtils {

    private static final SessionFactory sessionFactory = buildSessionFactory();

    private static SessionFactory buildSessionFactory() {
        try {
            // Create the ServiceRegistry from hibernate.cfg.xml
            ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder()
                    .configure("hibernate.cfg.xml").build();

            // Create a metadata sources using the specified service registry.
            Metadata metadata = new MetadataSources(serviceRegistry).getMetadataBuilder().build();

            return metadata.getSessionFactoryBuilder().build();
        } catch (Throwable ex) {
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    public static void shutdown() {
        // Close caches and connection pools
        getSessionFactory().close();
    }

}

And this was working until I upgraded my IDEA. Now I have some

Caused by: java.lang.ExceptionInInitializerError
    at org.mgo.HibernateUtils.buildSessionFactory(HibernateUtils.java:34)
    at org.mgo.HibernateUtils.getSessionFactory(HibernateUtils.java:11)
Caused by: org.hibernate.internal.util.config.ConfigurationException: Could not locate cfg.xml resource [/main/resources/hibernate.cfg.xml]

I tried everything I found with this error, to put the hibernate.cfg.xml directly into src folder, to point the path to the xml file like "/resources/hibernate.cfg.xml" or "/main/resources/hibernate.cfg.xml", or to leave it empty like this .configure() but nothing seems to work.

I found in here: https://github.com/spring-projects/spring-framework/issues/21340 something that it doesn't works with Spring 4.3.17.RELEASE + Hibernate 5.2.17.Final and works with Spring 5.0.6.RELEASE + Hibernate 5.1.14.Final but if I change like this I get many other errors and I don't get it why my hibernate.5.2.2.Final + spring.4.0.6.RELEASE doesn't works anymore because of my IDEA. As I am using Maven, I tried to compile outside of Idea but facing the same error...

huh, maybe this will help somebody... I did it without an hibernate.cfg.xml, like this: https://dzone.com/articles/hibernate-5-java-configuration-example

public class HibernateUtils {

    private static SessionFactory sessionFactory;

    public static SessionFactory getSessionFactory() {

        if (null == sessionFactory) {
            try {
                Configuration configuration = new Configuration();

                // Hibernate settings equivalent to hibernate.cfg.xml's properties
                Properties settings = new Properties();

                settings.put(Environment.DRIVER, "com.microsoft.sqlserver.jdbc.SQLServerDriver");
                settings.put(Environment.URL, "jdbc:sqlserver://localhost;databaseName=DBA;instance=SQLEXPRESS");
                settings.put(Environment.USER, "user");
                settings.put(Environment.PASS, "xxx");
                settings.put(Environment.DIALECT, "org.hibernate.dialect.SQLServerDialect");
                settings.put(Environment.SHOW_SQL, "true");
                settings.put(Environment.CURRENT_SESSION_CONTEXT_CLASS, "thread");

                configuration.setProperties(settings);

                configuration.addAnnotatedClass(MyClass1.class);
                configuration.addAnnotatedClass(MyClass2.class);

                ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder()
                        .applySettings(configuration.getProperties()).build();

                sessionFactory = configuration.buildSessionFactory(serviceRegistry);

            } catch (Exception e) {
                e.printStackTrace();
            }
        }
        return sessionFactory;
    }
}
