Broken Hibernate逆向工程任务，模糊错误消息

Question

我们有一个项目，它使用独立的Hibernate工具Ant任务来构建hbm.xml文件和POJO。当我们需要添加或更新POJO时，我们只运行Ant任务，它有自己的build.xml文件，而不是每次构建项目时。

其他人更新了项目，现在Ant任务（没有改变）不能解析构建文件（它也没有改变）。我无法知道这个变化是什么或者这个工作还没有进行多久，所以我要求社区帮助我诊断它。这里的消息：

这里的配置文件，它不能解析：

<?xml version="1.0" encoding="utf-8"?> 
<!DOCTYPE hibernate-configuration 
    PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" 
    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

Answer 1

这似乎是答案是：reveng.xml和reveng.cfg.xml文件被更新我们的常驻天才之一，将工作XML DTD定义替换为与项目中安装的Hibernate jar不匹配的定义。这里是正在为reveng.cfg.xml文件中的一个：

<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

这里是正在为reveng.xml文件中的一个：

<!DOCTYPE hibernate-reverse-engineering SYSTEM "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd">

这里有这被打破，那些没有工作：

<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<!DOCTYPE hibernate-reverse-engineering SYSTEM "http://www.hibernate.org/dtd/hibernate-reverse-engineering-3.0.dtd">

这是为Hibernate逆向工程3.3.1罐子。

我希望这可以帮助别人！
