Where did Configuration.generateSchemaCreationScript() go in Hibernate 5

Thanks to the answers by Vlad and Gunnar, I’ve managed to find my way through the new configuration API to produce the equivalent export logic with the following. Of course, history shows that this API will break again, so make sure to choose the appropriate version:

Hibernate 5.2:

MetadataSources metadata = new MetadataSources(
    new StandardServiceRegistryBuilder()
        .applySetting("hibernate.dialect", "org.hibernate.dialect.H2Dialect")
        .applySetting("javax.persistence.schema-generation-connection", connection)
        .build());

// [...] adding annotated classes to metadata here...
metadata.addAnnotatedClass(...);

SchemaExport export = new SchemaExport();
export.create(EnumSet.of(TargetType.DATABASE), metadata.buildMetadata());

Hibernate 5.2 (without warnings):

The above will produce some nasty warnings, which can either be ignored:

Okt 20, 2016 2:57:16 PM org.hibernate.engine.jdbc.connections.internal.ConnectionProviderInitiator initiateService
WARN: HHH000181: No appropriate connection provider encountered, assuming application will be supplying connections
Okt 20, 2016 2:57:16 PM org.hibernate.engine.jdbc.env.internal.JdbcEnvironmentInitiator initiateService
WARN: HHH000342: Could not obtain connection to query metadata : The application must supply JDBC connections

… or you work around them by hacking the following ConnectionProvider into the settings (it shouldn’t be required in my opinion)

        .applySetting(AvailableSettings.CONNECTION_PROVIDER, new ConnectionProvider() {
            @Override
            public boolean isUnwrappableAs(Class unwrapType) {
                return false;
            }
            @Override
            public <T> T unwrap(Class<T> unwrapType) {
                return null;
            }
            @Override
            public Connection getConnection() {
                return connection; // Interesting part here
            }
            @Override
            public void closeConnection(Connection conn) throws SQLException {}

            @Override
            public boolean supportsAggressiveRelease() {
                return true;
            }
        })

Hibernate 5.0:

MetadataSources metadata = new MetadataSources(
    new StandardServiceRegistryBuilder()
        .applySetting("hibernate.dialect", "org.hibernate.dialect.H2Dialect")
        .build());

// [...] adding annotated classes to metadata here...
metadata.addAnnotatedClass(...);

SchemaExport export = new SchemaExport(
    (MetadataImplementor) metadata.buildMetadata(),
    connection // pre-configured Connection here
);
export.create(true, true);

Hibernate 4:

As a reminder, here’s how this worked in Hibernate 4:

Configuration configuration = new Configuration()
    .setProperty("hibernate.dialect", "org.hibernate.dialect.H2Dialect");

// [...] adding annotated classes to metadata here...
configuration.addAnnotatedClass(...);

configuration.generateSchemaCreationScript(
    Dialect.getDialect(configuration.getProperties()));
SchemaExport export = new SchemaExport(configuration, connection);
export.create(true, true);
