问题描述
我已经从https://developers.google.com/gmail/api/quickstart/java下载了gmail快速入门演示。
我已经在Google Cloud Platform中注册，并加入了gmail api，创建了自己的项目和凭据...
当我全力以赴时，一切都会朝着正确的方向前进。下一秒，我陷入了麻烦。
第一次，我运行的是原始程序，如提供的网站一样。

if (labels.isEmpty()) {

} else {
System.out.println("Labels:");
for (Label label : labels) {

}
}
}
}
及其相关性如下：

有人可以帮助我解决吗？ 我真的很困惑，问题已经持续了几天，而且我还没有找到任何有用的文档。
