java - 使用 Java google apps 目录 API 获取特定电子邮件 ID 的组时出错

Question

我想借助 Java Google Apps Directory API 在 Google Apps 中获取特定电子邮件 ID 的群组，但出现错误。

有人可以帮助解释一下错误是什么以及我的代码中可能导致该错误的原因吗？错误及相关代码如下。

错误:

WARNING: Application name is not set. Call Builder#setApplicationName.
Exception in thread "main" com.google.api.client.auth.oauth2.TokenResponseException: 400 Bad Request

在您的新 GoogleCredential.Builder() 中调用 Builder#setApplicationName。
