Google BigQueryを使用しており、Compute Engineを使用していますか？

次のサイトで提供されているJavaのサンプルを、同じpom.xmlファイルとコードを使用して実行しようとしています。Google BigQueryを使用しており、Compute Engineを使用していますか？

https://cloud.google.com/bigquery/create-simple-app-api

私はそれは必要ないと思ったので、私はのpom.xmlから親要素を取り出しました。

私は以下のpom.xmlを掲載している：

私はCompute Engineのを使用する予定はありません、 Google BigQueryだけです

ありがとうございます。

この部分は読んでいますか？スレッド "main"の例外java.io.IOException：アプリケーションデフォルトの資格情報は使用できません。 Google App Engine、Google Compute Engine、Google Cloud Shellで実行している場合に利用できます。それ以外の場合は、環境変数GOOGLE_APPLICATION_CREDENTIALSを定義して、資格を定義するファイルを指定する必要があります。詳細については、[https://developers.google.com/accounts/docs/application-default-credentials](https://developers.google.com/accounts/docs/application-default-credentials）を参照してください。 –

もちろん、コンソールにサービスアカウントキーを作成してローカルに保存し、その環境変数を.jsonファイルで指定するだけです。あなたはこれを解決できましたか？ – Adam

これはもはや関連性がないと思うが、私の場合、IDEを再起動することで問題が解決されている。私はWindowsとIdeaをIDEとして使用しています。問題は、システム変数にGOOGLE_APPLICATION_CREDENTIALSを追加する前にIDEを実行していたことです。コマンドラインの実行中にシステム変数を追加すると、コマンドラインを再起動してシステム変数を有効にする必要があります
