java - 由于连接重置，Google App Engine 生成 Cloud Endpoint 失败

Question

我正在 Eclipse 上使用 GAE 开发 Android 应用程序。
我可以毫无错误地将应用程序部署到 App Engine，但最近当我尝试使用 Google 插件生成云端点客户端库时，它无法完成并且错误日志显示:“java.lang.reflect.InvocationTargetException ... Caused通过:java.net.SocketException:连接重置”

这是完整的 Exceptoin 堆栈跟踪:

eclipse.buildId=unknown
java.version=1.7.0_40
java.vendor=Oracle Corporation
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US
Command-line arguments:  -os win32 -ws win32 -arch x86

请访问 https://.appspot.com/_ah/api/explorer 检查您的应用程序是否在 App Engine 中可用

请同时验证您是否可以在资源管理器中调用您的 api。
