I suspect the following would need to be changed/added in the POM
<project>
<packaging>bundle</packaging>
<build>
<plugins>
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>4.1.0</version>
<extensions>true</extensions>
</plugin>
</plugins>
</build>
</project>
