Gradle无法找到com.google.android.gms：play-services：8.4.0

Question

我无法将Google Play游戏服务连接到我的libgdx项目。 Gradle说SDK没有Google Repository：

但我确实安装了它：

我的SDK路径有效

# Location of the android SDK
sdk.dir=D\:\\Android\\ADT\\sdk

我有来自

的google-play-services.jar

D:\Android\ADT\sdk\extras\google\google_play_services\libproject\google-play-services_lib\libs

但Gradle不承认。

我已经清理，重建，重新加载了存储库，但没有任何事情发生。

Stack说>>it<<可能对我有帮助，但不是。这不是我的情况。
