Probleme beim Erstellen der GCM Demo Server-Anwendung

Question

Wenn ich versuche, den GCM Demo Server from the documentation mit ant zu erstellen, erhalte ich 17 Kompilierungsfehler. Es scheint, dass einige GCM-Bibliotheken fehlen. Wie kann ich diese Probleme lösen?

Ich habe noch nie dieses Projekt selbst laufen, aber es sieht aus wie es die Bibliotheken von Extras \ Google fehlt \ gcm \ gcm-server \ dist \ gcm-server.jar und ihre Abhängigkeiten. Fügen Sie diese zum libs-Ordner unter diesem Projekt hinzu und versuchen Sie es erneut.
