Hi,
I'm trying to leverage hibernate3 maven plugin with a JPA mapping.
I tried running mvn hibernate3:hbm2ddl and I get a NullPointerException
somewhere during the loading of hibernate mappings...
Here's my plugin config:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>hibernate3-maven-plugin</artifactId>
<configuration>
<components>
<component>
<name>hbm2ddl</name>
<implementation>jpaconfiguration</implementation>
</component>
</components>
<componentProperties>
<jdk5>true</jdk5>
<ejb3>true</ejb3>
<persistenceunit>ReferenceDataManagerTestDB</persistenceunit>
<configurationfile>src/test/resources/META-INF/persistence.xml</configurationfile>
</componentProperties>
</configuration>
<executions>
<execution>
<phase>process-classes</phase>
<goals>
<goal>hbm2ddl</goal>
</goals>
</execution>
</executions>
<dependencies>
<dependency>
<groupId>${test.db.group}</groupId>
<artifactId>${test.db.artifact}</artifactId>
<version>${test.db.version}</version>
<scope>test</scope>
</dependency>
</dependencies>
</plugin>
Stacktrace:

I know my hibernate configuration and mapping load fine in a spring test unit
test environment and/or application server.
Can you please advise?
Thanks,
