Do you need to generate the metamodel classes for only a subset of your
entities, or will generating them for everything work?
Adding just this will generate the metamodel classes for everything (you had
most of this already) :
<build>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
<compilerArgument>-Aopenjpa.metamodel=true</compilerArgument>
</configuration>
</plugin>
</plugins>
</build>
If you only want metamodel classes for a subset of your entities you might
have to use <excludes> or <includes> in the configuration for the compiler
(and two different executions of the plugin). Of course there could be some
Maven wushu that I don't know that makes this easier.
