Im trying to generate my java-classes using hibernate-tools (3.0beta1), the eclipse-plugin works flawless but the ant-task won't produce any classes.

My ant-target (
Code:
   <target name="generate-pojo"
      description="Build the pojo's from hbm config">
      <hibernatetool destdir="${build.dir}/bottomup">
         
         <configuration configurationfile="${src.java.dir}/dao/hibernate.cfg.xml"><!--propertyfile="mainhibernate.properties"-->
            <fileset dir="${src.java.dir}/dao">
               <include name="**/*.hbm.xml" />
            </fileset>       
         </configuration>
         
         <hbm2java/>
      </hibernatetool>
   </target>

    <taskdef name="hibernatetool" classname="org.hibernate.tool.ant.HibernateToolTask">
       <classpath>
            <path refid="hibernatetool.classpath"/>
       </classpath>
   </taskdef>

    <path id="hibernatetool.classpath">
        <path refid="hibernate.classpath"/>
      <pathelement location="${hibernate.tools.dir}/hibernate-tools.jar"/>
      <pathelement location="${hibernate.tools.dir}/velocity-1.4.jar"/>
      <pathelement location="${hibernate.tools.dir}/velocity-tools-generic-1.1.jar"/>
      <pathelement location="${hibernate.tools.dir}/jtidy-r8-21122004.jar"/>
        <pathelement location="${commons-logging.jar}"/>
        <pathelement location="${commons-collections.jar}"/>
        <pathelement location="${log4j.jar}"/>
    </path>   



Running this gives me the following stacktrace when run in verbose.

Code:

the exporters run by the ant tasks are the same exporters that are run by the eclipse plug in. check to see if that ant tasks have different jar files in the classpath.

and use the hibernate that comes with the tools (in this case its h3.1 rc1, but much easier to just use the hibernate that comes with the tools)

note: you can still use another H3.x for your runtime stuff.

Thanks Max, this solved it.

I troubleshot it by copying all of the hibernate/*.jar files from the tool-directory, and put one jar in at a time. Using the hibernate3.jar delivered with the plug-in when generation the artifacts solved the problem.
