我一直在尝试使用Java生成Google Cloud图片网址的代码块，其中my-bucket是Google存储桶名称。
String key = "/gs/Buckets/my-bucket/photo/1/content.jpeg";
ImagesService imagesService = ImagesServiceFactory.getImagesService();
ServingUrlOptions options = ServingUrlOptions.Builder
.withGoogleStorageFileName(key)
.imageSize(100);
String servingUrl = imagesService.getServingUrl(options);
但我收到错误
Exception in thread "main" com.google.apphosting.api.ApiProxy$CallNotFoundException: The API package 'blobstore' or call 'CreateEncodedGoogleStorageKey()' was not found.

我已尝试过键值
String key = "/gs/Buckets/my-bucket/photo/1/content.jpeg";
和
String key = "/gs/my-bucket/photo/1/content.jpeg";
但是这会得到同样的错误。
