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"?>
<project name="HelloWorld" default="compile" basedir=".">
<property name="proj.name" value="HelloWorld"/>
<property name="proj.version" value="1.0"/>

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 /)
答案 0 :(得分:0)
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>
