我正在使用hibernate 4.0.0.CR4并尝试使用Hibernate的Java Persistence中的“Message”示例。我能够使用ant build编译和运行应用程序,但是当我尝试使用hibernatetool导出模式时,我收到错误

的build.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

错误:

/home/student/workspace/HelloWorld/build.xml:61: taskdef A class needed by class org.hibernate.tool.ant.EnversHibernateToolTask cannot be found: org/hibernate/tool/ant/HibernateToolTask

以下是我班级路径上的罐子:     ANTLR-2.7.7.jar     同学-0.5.4.jar     公地集合-3.2.1.jar     共享记录-1.1.1.jar     dom4j的-1.6.1.jar     休眠公地的注解,4.0.0.CR2.jar     休眠核心,4.0.0.CR4.jar     休眠-envers-4.0.0.CR4.jar     冬眠-JPA-2.0-API-1.0.1.Final.jar     的hsqldb.jar     jandex-1.0.3.Final.jar     Javassist进行-3.12.1.GA.jar     JBoss的日志记录,3.0.0.GA.jar     JBoss的事务-api_1.1_spec-1.0.0.Final.jar

在几个论坛上我发现缺少的类是hibernate-tools.jar的一部分,但我在hibernate的版本中找不到这个jar(http://sourceforge.net/projects/hibernate/files/hibernate4/ 4.0.0.CR4 /)

您应该在

中设置节点
<target name="schemaexport" depends="compile, copymetafiles"
    description="Exports a generated schema to DB and files">
    <taskdef name="hibernatetool" classname="org.hibernate.tool.ant.HibernateToolTask"
        classpathref="project.classpath"/>

    <hibernatetool destdir="${basedir}">
        <classpath path="${build.dir}"/>
        <configuration configurationfile="${build.dir}/hibernate.cfg.xml"/>
        <hbm2ddl
            drop="true"
            create="true"
            export="true"
            outputfilename="helloworld-ddl.sql"
            delimiter=";"
            format="true"/>
    </hibernatetool>
</target>
