 Post subject: Problems generating annotation using <hbmtemplate> in

I am having problems using the <hbmtemplate> goal in Maven, but only when I want to generate annotations. I have also successfully been able to generate the pojos with the same configuration using Hibernate Tools plugin(Version: 3.2.4.Alpha1) for Eclipse.

I have modified the freemarker templates to add the ability to generate oracle sequence annotations, otherwise they are copy of what is in the distribution.

Here is the hibernate tools entry in my pom.xml:

Code:
      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>hibernate3-maven-plugin</artifactId>
        <version>2.0-alpha-2</version>
        <executions>
          <execution>
            <phase>process-test-resources</phase>
            <goals>
              <goal>hbm2ddl</goal>
            </goals>
          </execution>
        </executions>
        <dependencies>
          <dependency>
            <groupId>${jdbc.groupId}</groupId>
            <artifactId>${jdbc.artifactId}</artifactId>
            <version>${jdbc.version}</version>
          </dependency>
        </dependencies>
        <configuration>
          <componentProperties>
            <jdk5>true</jdk5>
            <ejb3>true</ejb3>
            <revengfile>${basedir}\hib-gen\hibernate.reveng.xml</revengfile>
            <configurationfile>${basedir}\hib-gen\hibernate.cfg.xml</configurationfile>
            <outputfilename>${basedir}\src\main\java</outputfilename>
            <templatepath>${basedir}\hib-gen\ftl\pojo</templatepath>
            <propertyfile>${basedir}\hib-gen\hibernate.properties</propertyfile>
         <filepattern>{package-name}\{class-name}.java</filepattern>
         <template>Pojo.ftl</template>           
            <packagename>com.intellidyne.rms.model</packagename>
            <skip>false</skip>
          </componentProperties>
        </configuration>
      </plugin>


And here is the resulting exception I receive in the maven logs:

Code:
07:50:49,902  INFO org.hibernate.tool.Version - Hibernate Tools 3.2.0.b9
07:50:50,230 ERROR freemarker.runtime -

If I switch the configuration to not use ejb3, then the pojos are successfully generated. Any help to what I am doing wrong would be appreciated.

I added a dependency to an earlier version to Hibernate Tools in the pom and it seemed to fix the problem. Guess this issue is isolated to the latest version.

This is what I added:

Code:
          <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-tools</artifactId>
            <version>3.2.0.ga</version>
          </dependency>
