在Java API中复制到目标Google Cloud Bucket时，是否可以提供该目标的凭据？

import com.google.auth.oauth2.GoogleCredentials;
import com.google.cloud.storage.Blob;
import com.google.cloud.storage.BlobId;
import com.google.cloud.storage.Storage;
import com.google.cloud.storage.StorageOptions;

import java.io.FileInputStream;
import java.io.IOException;

public class GoogleCloudStorageExample {
    public static void main(String[] args) throws IOException {
        // 从服务账号密钥文件中创建凭据
        GoogleCredentials credentials = GoogleCredentials.fromStream(new FileInputStream("path/to/service-account-key.json"));

        // 创建Google Cloud Storage客户端
        Storage storage = StorageOptions.newBuilder().setCredentials(credentials).build().getService();

        // 复制文件到目标Google Cloud Bucket
        BlobId sourceBlobId = BlobId.of("source-bucket", "source-object");
        BlobId targetBlobId = BlobId.of("target-bucket", "target-object");
        Blob targetBlob = storage.copy(sourceBlobId, targetBlobId);

        System.out.println("文件复制成功：" + targetBlob.getName());
    }
}
