Eclipse + maven + hibernate-tools 逆向工程错误

问：

我正在尝试使用 hibernate-tools 套件的逆向工程工具在 PostgreSQL 数据库中生成表的所有模型。

我 https://www.codejava.net/frameworks/hibernate/java-hibernate-reverse-engineering-tutorial-with-eclipse-and-mysql 遵循了本指南，但是当我运行休眠代码生成器时，它显示此错误：

org.jboss.tools.hibernate.runtime.spi.HibernateException: Table(public.newtable) already has a primary key!
    at org.hibernate.eclipse.console.workbench.LazyDatabaseSchemaWorkbenchAdapter$2.execute(LazyDatabaseSchemaWorkbenchAdapter.java:132)
    at org.hibernate.console.execution.DefaultExecutionContext.execute(DefaultExecutionContext.java:63)
    at org.hibernate.console.ConsoleConfiguration.execute(ConsoleConfiguration.java:107)
    at org.hibernate.eclipse.console.workbench.LazyDatabaseSchemaWorkbenchAdapter.readDatabaseSchema(LazyDatabaseSchemaWorkbenchAdapter.java:119)
    at org.hibernate.eclipse.console.workbench.LazyDatabaseSchemaWorkbenchAdapter.getChildren(LazyDatabaseSchemaWorkbenchAdapter.java:60)
    at org.hibernate.eclipse.console.workbench.BasicWorkbenchAdapter.fetchDeferredChildren(BasicWorkbenchAdapter.java:104)
    at org.eclipse.ui.progress.DeferredTreeContentManager$1.run(DeferredTreeContentManager.java:219)
    at org.eclipse.core.internal.jobs.Worker.run(Worker.java:63)

这是 newtable DDL

CREATE TABLE public."newtable" (
    "codiceFiscale" varchar(16) NOT NULL,
    nome varchar(100) NULL,
    cognome varchar(100) NULL,
    email varchar(255) NULL,
    indirizzo varchar(255) NULL,
    "idComune" int4 NULL,
    "idStato" varchar(3) NULL,
    "idProvincia" int4 NULL,
    cap varchar(10) NULL,
    "ruolo" varchar(1) NULL,
    "idAccount" int4 NULL,
    username varchar(100) NULL,
    rup varchar(10) NULL,
    "codice" varchar(20) NULL,
    "codiceNUTS" varchar(20) NULL,
    "codiceStatoExtraUE" varchar(100) NULL,
    "dataAbilitazione" timestamp NULL,
    "dataRegistrazione" timestamp NULL,
    "numeroRinnovo" int4 NULL,
    CONSTRAINT newtable_pk PRIMARY KEY ("codiceFiscale")
);

这就是冬眠.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
        <property name="hibernate.connection.password">XXXXXXXXXXXXXXXXXXX</property>
        <property name="hibernate.connection.url">jdbc:postgresql://XXX.XXX.XXX.XXX:5432/test</property>
        <property name="hibernate.connection.username">postgres</property>
        <property name="hibernate.default_schema">public</property>
        <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>
    </session-factory>
</hibernate-configuration>

可以毫无问题地处理其他表。 有什么建议吗？

编辑

通过删除 DDL 中表名和列名两边的双引号，凭经验求解
