내가클라우드 음성 API 샘플에서 예외가 발생합니다 : java.net.UnknownHostException :에 의한 accounts.google.com
에서 예제 코드 다음 음성을 인식 Google 클라우드 음성 API를 사용하려고 해요https://github.com/GoogleCloudPlatform/java-docs-samples/tree/master/speech/grpc
나는 here에서 설명한대로 지침과 작성된 자격 증명 (서비스 계정 키)을 작성하고 결제 계정을 만들었습니다.
mvn clean install 명령을 실행할 때 테스트 케이스 실행을 시작합니다. 다음과 같은 오류가 발생합니다 :
