在Flink用OSS存储checkpoint
OssCheckpointStorage 找不到依赖呢？我用的POM的项目，网上的代码， 找不到OssCheckpointStorage的依赖

// 配置OSS的checkpoint存储路径
    String ossEndpoint = "oss-cn-shanghai.aliyuncs.com"; // OSS的endpoint
    String ossAccessKeyId = "your_access_key_id"; // 你的OSS Access Key ID
    String ossAccessKeySecret = "your_access_key_secret"; // 你的OSS Access Key Secret
    String bucket = "your_bucket"; // OSS的bucket名称
    String path = "your_checkpoint_path/"; // OSS上的checkpoint目录
    env.getCheckpointConfig().setCheckpointStorage(new OssCheckpointStorage(ossEndpoint, ossAccessKeyId, ossAccessKeySecret, bucket, path));
