Problemas al construir la aplicación del Servidor de Demostración GCM

Question

Cada vez que intento construir el servidor de demostración de GCM a partir de la documentación que utiliza ant , obtengo 17 errores de compilación. Parece que faltan algunas bibliotecas de GCM. ¿Cómo puedo resolver estos problemas?

Nunca he ejecutado este proyecto yo mismo, pero parece que le faltan las bibliotecas de extras / google / gcm / gcm-server / dist / gcm-server.jar y sus dependencias. Añádalos a la carpeta libs en este proyecto y vuelva a intentarlo.
