找不到Hibernate 6 SchemaExport类

Question

我使用类似于导出JPA实体模式DDL的代码：

import org.hibernate.tool.hbm2ddl.SchemaExport;
import org.hibernate.tool.hbm2ddl.SchemaUpdate;

public class HibernateQueryGenerator {
    public static void main(String[] args) {
//        createSchema();
        updateSchema();
    }

    private static void addEntityClass(MetadataSources metadata) {
        // Scan entity packages and use : 
        // metadata.addAnnotatedClass(...);
    }

    private static void updateSchema() {
        MetadataSources metadata = getMetadataSources();
        SchemaUpdate schemaUpdate = new SchemaUpdate();
        schemaUpdate.setHaltOnError(true);
        schemaUpdate.setFormat(false);
        schemaUpdate.setDelimiter(";");
        schemaUpdate.execute(EnumSet.of(TargetType.STDOUT), 
        metadata.buildMetadata());
    }

    private static void createSchema() {
        MetadataSources metadata = getMetadataSources();
        SchemaExport schemaExport = new SchemaExport();
        schemaExport.setHaltOnError(true);
        schemaExport.setFormat(false);
        schemaExport.setDelimiter(";");
        schemaExport.execute(EnumSet.of(TargetType.STDOUT), SchemaExport.Action.CREATE, metadata.buildMetadata());
    }

    private static MetadataSources getMetadataSources() {
        MetadataSources metadata = new MetadataSources(
                new StandardServiceRegistryBuilder()
                        .applySettings(getSettings())
                        .build());
        addEntityClass(metadata);
        return metadata;
    }

    private static Map<String, String> getSettings() {
        Map<String, String> settings = new HashMap<>();
        settings.put("connection.driver_class", "org.postgresql.Driver");
        settings.put("dialect", "org.hibernate.dialect.PostgreSQL10Dialect");
        settings.put("hibernate.connection.url", "jdbc:postgresql://172.22.0.3:5432/tutorial");
        settings.put("hibernate.connection.username", "admin");
        settings.put("hibernate.connection.password", "adminpass");
        return settings;
    }

    private static void sleep() {
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}         

我在Hibernate 6中找不到SchemaExport和SchemaUpdate类。

这门课被降级了吗？

什么是替代？

这些类是hibernate-ant模块：https://search.maven.org/artifact/org.hibernate.orm/hibernate-ant/6.1.4.Final/jar的一部分。
