我正在尝试使用Google Cloud Translate API。我从服务帐户生成了JSON文件，并将设置GOOGLE_APPLICATION_CREDENTIALS为JSON文件的保存位置。然后，我在这样的程序中使用了它：

import com.google.cloud.translate.*;
...
Translate translate = TranslateOptions.getDefaultInstance().getService();
Translation translation = translate.translate(message);

但我收到以下错误

com.google.cloud.translate.TranslateException: Your application has authenticated using end user credentials from the Google Cloud SDK or Google Cloud Shell which are not supported by the translate.googleapis.com. We recommend that most server applications use service accounts instead.
