Why doesn't Hibermate create tables?
In general, I study Hibernate. I'm trying to create tables in the database, I seem to have done everything as in the tutorial, but there are no records about creating tables. Here is what is output in the console.

Maybe someone else will come in handy, because the behavior is rather non-obvious and is not explained anywhere.
I'm just getting started with java and decided to use Java SE8, Hibernate 5.1, JPA for a small desktop application.
Generate a database schema from annotated entity classes using SchemaExport from the command line.
SchemaExport does not yet support annotated entity classes out of the box, it waits for old *.hbm.xml mapping files.
The command has a simple syntax
All options options can be found in the org.hibernate.tool.hbm2ddl.SchemaExport class, lines 499 to 551. Everything is clear there.
If you are using hibernate.cfg.xml, you can specify this file in the --config option.
This HibernateUtil class is just a small example. It only generates SQL commands and inserts them into the init.sql file.
You can make a wrapper class for SchemaExport to have all its features, just come up with some option to add annotated entity classes. Although, if they ask me, then I can write such a class, it's not difficult at all.
The core-team says that they don't have time to deal with tools for hibernate now, so it's not known how long to wait for this change from them.
Just a whole article turned out, I hope it will be useful to someone.
