NoClassDefFoundError: ligne com/Google/api/client/auth/oauth2/informations d'identification

Question

Ajout du suggested (s):

CountDownLatch latch = new CountDownLatch(1); 
.. 
latch.countDown(); 
latch.await(); 

entourant la requête de base de données expose l'exception suivante après ant jar de Netbeans:

Pour autant que je peux dire ce sont les correct paquets, mais apparemment pas parce qu'il n'y a pas de classe Credential:

Où puis-je télécharger le JAR avec cette classe spécifique? Exception se produit indépendamment de si exécuté de l'interface de ligne de commande à travers ant run, en exécutant le fichier JAR directement comme ci-dessus ou en utilisant Netbeans.

Answer 1

classe ajouté à Verson 1.7 voir java docs
