何が起きているのか理解していないうちにこの問題が発生しています。IntelliJでsbtベースのプロジェクトをインポートし、IntelliJクラスパスにプロジェクトリソース（src/main/resources）がありません。その結果、nullを返すために.getClass.getResource(...)が呼び出されます。 
IntelliJ IDEA/Scala：クラスパス上のコンフィグレーションミスリソースを実行する
私は.ideaを削除し、私は、以前のIntelliJのバージョンから既存の.ideaをアップグレードからのキャッシングの問題を疑ってるとして新たにプロジェクトを作成する傾向があります。しかし今日は運がない。時には.getResourceから.getResourceAsStreamに変更すると解決するようですが、今日はもう運がありません。プロジェクト設定の確認
、ディレクトリが正しく「資源」としてトグルする：
し、実行コンフィギュレーションを確認し、モジュール/クラスパスが正しく選択されています
言うまでもなく、端末からのsbt test:runを使用すると、期待どおりに動作し、リソースが見つかります。
