java - 使用 Google 的 Java API 客户端库进行身份验证时出现 IllegalArgumentException

Question

我正在尝试运行 QuickStart.java https://developers.google.com/sheets/api/quickstart/java在 NetBeans 8.2 上。我已经导入了所有 Google 库，但遇到了这个问题

我也遇到了同样的错误。我一直在使用服务帐户 key 而不是OAuth 2.0 客户端ID

使用从 https://console.developers.google.com/apis/ 获取的 OAuth 2.0 客户端 ID工作并能够阅读表格。
