ClientConfiguration clientConfig = new ClientConfiguration()

IBM-COS-javaの-SDK-コア-1.1.0とIBM-COS-javaの-SDK-s3-1.1.0

私はこの問題を解決したい。 フィールドからのリソース：ibm-cos-java-sdk

ibm-cos-java-sdkを使用してIBM Cloud Object Storageにアクセスしたいとします。

Answer 1

これは、コードに適切な依存関係を使用していないようです。だけでなく、あなたはすでに試した何を - あなたはMavenを使用している場合

は、完全に実際の問題と目的が何であるかを説明するようにしてくださいのpom.xml
