Tengo un proyecto de múltiples módulos Maven OSGi. El proyecto funciona perfectamente bien cuando OSGi selecciona los frascos de los módulos individuales del proyecto.(ver 1.1.B abajo).

Sin embargo, usando un segundo enfoque,bundle.getRegisteredServices() (ver 1.1.A a continuación) devuelve nulo cada vez que intento usar paquetes depositados en una carpeta central(D: / padre / proveedor / destino / módulos) utilizando laMaven-Assembly-Plugin versión: 2.6:

framework.getBundleContext().installBundle("file:D:/parent/provider/target/modules/OSGiDmHelloWorldProvider-1.0.jar");
framework.getBundleContext().installBundle("file:D:/parent/provider/target/modules/OSGiDmHelloWorldConsumer-1.0.jar");

Ver 1.1.C a continuación para la salida de la consola utilizando el segundo enfoque.

1.1.A

if (bundle.getRegisteredServices() != null) {
    for (ServiceReference<?> serviceReference : bundle.getRegisteredServices())
        System.out.println("\tRegistered service: " + serviceReference);
}

¿Por qué no puedo acceder a los paquetes con el segundo enfoque?

Tengo un SSCCE enGitHub AQUÍ. Ejecutar la clase principal mostrará mi situación.

Gracias a todos de antemano.
