【问题描述】：
我正在尝试使用 Google + 中提供的域 API，我正在尝试使用域范围委派来快速启动 java 我已按照步骤操作，并且我已要求我的域管理员授予对我在控制台创建的项目，恢复我可以编译java文件，但是当我运行时，我得到一个404错误，这里是代码：

我迷路了，如果有人可以帮助我，我将不胜感激。
【问题讨论】：
-
您是在 Google Cloud Console 还是在旧版 Google APIs Console 中创建了您的客户端 ID？
-
Java 快速入门中的链接似乎是较旧的 Google API 控制台，当我将鼠标悬停在链接中时，这是地址：developer.google.com/console，但我没有点击该链接，我转到较旧的控制台，在您发表评论后，我单击链接并被带到我未使用的其他控制台，有区别吗？
-
我最近听说新控制台中的服务帐户凭据无法正常工作的问题。但不确定是否仍然如此。
-
好吧，我将尝试其他选项，您是否在第一次回复中看到我对我用来创建客户端 ID 的服务的评论？你认为这可能是个问题吗？
-
对我来说更奇怪的是响应是404错误未找到，不是授予访问的问题，看起来有些东西坏了，但我必须使用所有的建议和选项.
