Hibernate SchemaExport doesn't generate sql script

Could anybody please help me and give an idea why the code below doesn't generate SQL creation script? Hibernate version is 5.2.9.Final. I tried different approaches, used exact class names, package location, connection to an existing database but unfortunately, no one of them works for me. All code snippets I found on the internet looks like my one.

Class<PostgreSQL95Dialect> dialect = PostgreSQL95Dialect.class;

        StandardServiceRegistry registry = new StandardServiceRegistryBuilder()
            .applySetting(Environment.DIALECT, dialect)
            .build();

        MetadataSources metadataSources = new MetadataSources(registry);

        Set<Class<?>> entities = new Reflections("").getTypesAnnotatedWith(Entity.class);
        entities.forEach(e -> metadataSources.addAnnotatedClass(e.getClass()));

        System.out.println(String.format("entities : %d", entities.size()));

        Metadata metadata = metadataSources.buildMetadata();

        new SchemaExport()
            .setFormat(true)
            .setDelimiter(";")
            .setOutputFile(String.format("ddl_%s.sql ", dialect.getSimpleName()))
            .execute(EnumSet.of(TargetType.STDOUT, TargetType.SCRIPT), SchemaExport.Action.BOTH, metadata);

        StandardServiceRegistryBuilder.destroy(registry);

The result of code execution is below

I would be grateful for any help.

Solution

Finally, I have found a root of evil :)

I created a test Entity and tried to generate script only for it and the code worked! So the only possible place with a mistake is in getting classes with the help of reflection. And shame on me, how inattentive I was. Instead of writing

entities.forEach(e -> metadataSources.addAnnotatedClass(e.getClass()));

I need this

entities.forEach(e -> metadataSources.addAnnotatedClass(e));

First one will always give

class java.lang.Class
