Я совершенно новый пользователь, используя google-cloud-java .
Попытка сделать Speech Recognition с помощью google-cloud-speech .
Я написал приведенный ниже код, но есть проблема, я не знаю, как указать учетные данные, поэтому я получаю приведенную ниже ошибку, не знаю, как это сделать, и поиск в Интернете 2 часа сейчас:
java.io.IOException: The Application Default Credentials are not available. They
are available if running in Google Compute Engine. Otherwise, the environment v
ariable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defini
ng the credentials. See https://developers.google.com/accounts/docs/application-
default-credentials for more information.

Следуя приведенным ответам до настоящего времени
Мой credentials.json выглядит, и я получаю сообщение об ошибке:
