JAXB2 Maven Plugin cannot generate annotations or inject-code - maven-2

Question

I currently have an ant task that does a great job of generating my domain objects from xsd and xjb binding files. It creates the annotations and injects code where I need it based upon a custom Plugin.
Now I'm trying to move all of this to Maven and while I can generate the objects I cannot get the code to inject or add the annotations. My POM plugin entry is as follows:
<plugin>
<groupId>org.jvnet.jaxb2.maven2</groupId>
<artifactId>maven-jaxb2-plugin</artifactId>
<version>0.8.0</version>
<executions>
<execution>
<goals>
<goal>generate</goal>
</goals>
</execution>
</executions>
<configuration>
<bindingDirectory>src/main/resources/jaxb/bindings</bindingDirectory>
<generatePackage>com.noush.web.domain.model.data</generatePackage>
<extension>true</extension>
<verbose>true</verbose>
<args><!-- <arg>-XtoString</arg> -->
<!-- I want to use commons-lang-plugin to generate toString but this can
wait <arg>-Xcommons-lang</arg> <arg>-Xcommons-lang:ToStringStyle=SIMPLE_STYLE</arg> -->
<arg>-Xannotate</arg>
<arg>-Xinject-code</arg>
</args>
<plugins>
<plugin>
<groupId>noush</groupId>
<artifactId>code-expander-plugin</artifactId>
<version>1.0</version>
</plugin>
<plugin>
<groupId>org.jvnet.jaxb2_commons</groupId>
<artifactId>jaxb2-basics-annotate</artifactId>
<version>0.6.0</version>
</plugin>
</plugins>
</configuration>
</plugin>
The objects get created but without any injected code or annotations. The output doesn't give any indication that anything is wrong.
If it helps here is my working ant config:
<target name="defineXjcTask">
<taskdef name="xjc" classname="com.sun.tools.xjc.XJCTask" classpathref="xjcLib" />
</target>
<target name="generateJaxb">
<xjc target="${build.generated}" package="${noushweb.domain.model.jaxb.package}">
<arg value="-verbose"/>
<arg value="-extension"/>
<arg value="-Xcommons-lang"/>
<arg value="-Xcommons-lang:ToStringStyle=SIMPLE_STYLE"/>
<arg value="-Xinject-code"/>
<arg value="-Xannotate"/>
<schema dir="${build.directory}/jaxb/bindings" includes="${matmWS.mmmws.data.filename}" />
<binding dir="${build.directory}/jaxb/bindings" includes="${matmWS.mmmws.binding.filename}"/>
<produces dir="${build.generated}/${noushweb.domain.model.jaxb.package.dir}" includes="**/*.java" />
</xjc>
</target>
<path id="xjcLib">
<pathelement location="${lib.dir}/jaxb-ri-2.0.5/lib/jaxb-xjc.jar" />
<pathelement location="${ib.dir}/jaxb-ri-2.0.5/lib/jaxb-api.jar" />

<pathelement location="../lib/jaxb2-basics-annotate-0.6.0.jar" />
<pathelement location="../lib/annox-0.5.0.jar" />
<pathelement location="${lib.dir}/axis-1_4/lib/commons-logging-1.0.4.jar" />
<pathelement location="${lib.dir}/hibernate-validator-4.1.0.Final/hibernate-validator-4.1.0.Final.jar"/>
<pathelement location="${lib.dir}/hibernate-validator-4.1.0.Final/validation-api-1.0.0.GA.jar"/>
</path>
I guess I could use a antrun kind of setup but I was hoping I could get this to work.
Any thoughts would be most welcome.
Thanks
