Hibernate version:
3.1 beta1
hibernate-tools 3.1 alpha5

I have tried to generate mapping files from my annotated classes, to use the eclipse-plugin.

ant-task:
Code:
<target name="hibernatetool"
      description="generates hbm file">
      <taskdef
                 name="hibernatetool"
                 classname="org.hibernate.tool.ant.HibernateToolTask">
                 <classpath>
                    <fileset dir="${dir.lib}">
                       <include name="**/*.jar"/>
                    </fileset>
                    
                 </classpath>
      </taskdef>      
        <hibernatetool destdir="${dir.cfg}/hibernate/output">
           <classpath> <!-- a classpath is optional, but needed for generators that require access to domain classes etc. -->
               <fileset dir="${dir.lib}/hibernate">
                  <include name="**/*.jar"/>
                  <include name="**/*cfg.xml"/>
               </fileset>
              <fileset dir="${dir.cfg}/hibernate">
                 <include name="**/*cfg.xml"/>                 
              </fileset>
              <fileset dir="${dir.build}">
                 <include name="**/*.class"/>
              </fileset>
               <path location="${dir.build}"/>
              <path location="${dir.cfg}/hibernate"/>
            
           </classpath>      
           <annotationconfiguration configurationfile="./cfg/hibernate/hibernate.cfg.xml"/> <!-- annotated class/packages are specified in the hibernate.cfg.xml -->
                        <!--cfg2cfgXml/-->
           <cfg2hbm/>
        </hibernatetool>
      
   </target>



the build failed with the following error message:
"Error while processing template hbm/many-to-one.hbm.vm"

[hibernatetool] SCHWERWIEGEND: Method getJavaTypeName threw exception for reference $c2j in template hbm/many-to-one.hbm.vm at  [3,20]

BUILD FAILED
C:\Nils-Daten\Entwicklung\Diplom\build.xml:75: org.hibernate.tool.hbm2x.ExporterException: Error while processing template hbm/many-to-one.hbm.vm

Total time: 2 seconds


Could anyone tell me, if this is caused by a bug or misconfiguration?
Is there a way to get a more verbose explanation what went wrong?
The debug mode did not give more information about the error.

Thanks in advance.

Nils

probably a bug - we cfg2hbm is currently only built to handle what reverse engineering can output.

Coming from annotations to hbm.xml probably require more things to be added....feel free to submit a failing testcase and even better a patch for it ;)
