我的Hibernate逆向工程流程根本不提取数据库元数据。 如果我使用hibernate工具eclipse向导，该过程工作正常，但在eclipse之外，我无法使用我的ant构建文件
<taskdef name="hibernatetool" classname="org.hibernate.tool.ant.HibernateToolTask" />
<target name="generate">
<hibernatetool destdir="src">
<jdbcconfiguration propertyfile="hibernate.properties" revengfile="hibernate.reveng.xml" />
<hbm2hbmxml />
<hbm2cfgxml ejb3="true" />
<hbmlint destdir="src" />
<hbm2hbmxml destdir="src" />
</hibernatetool>
<hibernatetool destdir="src">
<configuration configurationfile="src/hibernate.cfg.xml" />
<hbm2java destdir="src" />
<hbm2dao destdir="src" />
</hibernatetool>
如果我正在尝试获取架构的远程数据库有连接，那么这不会失败。 该数据库是IBM DB2 Express-C，并且使用的是hibernate工具3.2。
我需要将其作为一个独立的进程运行，因为我希望将来通过不同的数据库生成基于JPA的数据层。目前，我的蚂蚁（详细）日志是：
