hibernate3-maven-plugin:hbm2java - Setup Problems

[Roye, Suhneel BGI SF]

I am trying to set up the Hibernate3 plugin for Maven2. Specifically, I
would like to have the plugin generate POJO's from *.hbm.xml mapping
files.

Relevant portions of my project directory structure:
Hibernate Configuration: <project>/src/main/resources/hibernate.cfg.xml
Hibernate Mappings:
<project>/src/main/resources/com/mycompany/app/*.hbm.xml
Target directory for generated POJO's:
<project>/src/main/java/com/mycompany/app/*.java

POM snippet:
.
.
.
    <pluginRepositories>
        <pluginRepository>
            <id>snapshots</id>
            <url>http://snapshots.maven.codehaus.org/maven2</url>
        </pluginRepository>
    </pluginRepositories>

.
.
.
            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>hibernate3-maven-plugin</artifactId>
                <configuration>
                    <hibernate>
 
<configurationFile>/src/main/resources/hibernate.cfg.xml</configurationF
ile>
                    </hibernate>
                    <outputDirectory>
                        <hbm2java>/src/main/java</hbm2java>
                    </outputDirectory>
                </configuration>
            </plugin>
.
.
.

Hibernate configuration snippet:
.
.
.
                <mapping resource="com/mycompany/app/TableOne.hbm.xml"/>
                <mapping resource="com/mycompany/app/TableTwo.hbm.xml"/>
                <mapping
resource="com/mycompany/app/TableThree.hbm.xml"/>
.
.

When I run "mvn hibernate3:hbm2java", I get an error and no POJO's are
generated. The top of my stack trace is:
java.lang.ExceptionInInitializerError
        at
org.codehaus.mojo.hibernate3.exporter.Hbm2JavaGeneratorMojo.createExport
er(Hbm2JavaGeneratorMojo.java:52)

Can someone please point out what I'm missing or doing wrong?

Thanks.
