Problemy z budową aplikacji serwera demonstracyjnego GCM

Question

Zawsze, gdy próbuję zbudować serwer demonstracyjny GCM from the documentation, używając ant, otrzymuję 17 błędów kompilacji. Wygląda na to, że brakuje niektórych bibliotek GCM. Jak mogę rozwiązać te problemy?

Nigdy nie uruchomić ten projekt samodzielnie, ale wygląda na to, że brakuje bibliotek z dodatkami \ Google \ GCM \ GCM-server \ dist \ GCM-server.jar i jego zależności. Dodaj je do folderu libs w ramach tego projektu i spróbuj ponownie.
