eu creio q o erro está mesmo na linha:

Initial SessionFactory creation failed.java.lang.NoClassDefFoundError: Hiber/Amigos (wrong name: hiber/Amigos)
Exception in thread “main” java.lang.ExceptionInInitializerError

pelo que eu entendi ele não está encontrando a classe Hiber/Amigos que está declarada no arquivo hibernate.cfg.xml na clausula mapping resource
assim como abaixo:

sera que há um problema na estrutura de diretorios??
pq sera q o hibernate nao esta encontrando este arquivo??

public class AmigosDAO {
    private static final SessionFactory factory;
    
    static {
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            factory = new Configuration().configure().buildSessionFactory();
        } catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);

    }
    
    public static SessionFactory getSessionFactory() {
        return factory;
