因此，当我将代码部署到CloudBees global.java时将无法运行（Play Framework 2.1）

Question

我只是在玩弄Google Drive API（云存储）并弄清楚它是如何工作的，我在play框架中编写了一些代码，其中在global.java onStart中获得了对驱动器的访问权限，并将测试文档写入了该驱动器。 在本地这可以正常工作，但是当我将代码部署到新的CloudBees应用程序并访问该应用程序时，我在日志中收到此错误，而我只是想不出如何对其进行调试：

Play server process ID is 7454
Oops, cannot start the server.

Google访问令牌仅可使用1个小时。 似乎您实际上并没有在请求带有刷新令牌的访问令牌。相反，似乎您正在设置已经发出的令牌。

您需要请求获取访问令牌（使用刷新令牌）

“乐趣”是，一旦您使用刷新令牌生成新的访问令牌，旧的访问令牌就会失效……或者至少这是我发现的经验……
