VOD-视频点播引用最新版的java SDK，vod的demo无法运行。为什么？

VOD-视频点播引用最新版的java SDK，vod的demo无法运行。大概看了一下没有com.aliyun.vod20170321...的包，只有com.aliyuncs....的引用。这是啥问题？POM引用如下： com.aliyun aliyun-java-sdk-core 4.6.0

    java.util.List<String> args = java.util.Arrays.asList(args_);
    com.aliyun.vod20170321.Client client = Sample.initVodClient(com.aliyun.darabonba.env.EnvClient.getEnv("ACCESS_KEY_ID"), com.aliyun.darabonba.env.EnvClient.getEnv("ACCESS_KEY_SECRET"), args.get(0));
    // 1.获取视频上传地址和凭证，并生成视频信息
    CreateUploadVideoRequest createUploadVideoRequest = new CreateUploadVideoRequest()
            .setTitle(args.get(1))
            .setFileName(args.get(2));
    CreateUploadVideoResponse createUploadVideoResponse = client.createUploadVideo(createUploadVideoRequest);
    com.aliyun.teaconsole.Client.log(com.aliyun.teautil.Common.toJSONString(TeaModel.buildMap(createUploadVideoResponse)));
    // 媒体id
    String uploadVideoId = createUploadVideoResponse.body.videoId;
    com.aliyun.teaconsole.Client.log(uploadVideoId);
    // 如果视频文件过大，上传超时后可以刷新视频凭证，然后继续上传
    RefreshUploadVideoRequest refreshUploadVideoRequest = new RefreshUploadVideoRequest()
            .setVideoId(uploadVideoId);
    RefreshUploadVideoResponse refreshUploadVideoReponse = client.refreshUploadVideo(refreshUploadVideoRequest);
    com.aliyun.teaconsole.Client.log(com.aliyun.teautil.Common.toJSONString(TeaModel.buildMap(refreshUploadVideoReponse)));
    // 2.oss视频文件上传，需要用户实现
    // 3.上传过程中，获取媒体上传详情
    GetUploadDetailsRequest getUploadDetailsRequest = new GetUploadDetailsRequest()
            .setMediaIds(uploadVideoId);
    GetUploadDetailsResponse getUploadDetailsReponse = client.getUploadDetails(getUploadDetailsRequest);
    com.aliyun.teaconsole.Client.log(com.aliyun.teautil.Common.toJSONString(TeaModel.buildMap(getUploadDetailsReponse)));
    // 4.媒体上传完成之后，可以获取媒体播放信息进行播放
    // 4.1 通过播放凭证播放
    GetPlayInfoRequest getPlayInfoRequest = new GetPlayInfoRequest()
            .setVideoId(uploadVideoId);
    GetPlayInfoResponse getPlayInfoReponse = client.getPlayInfo(getPlayInfoRequest);
    com.aliyun.teaconsole.Client.log(com.aliyun.teautil.Common.toJSONString(TeaModel.buildMap(getPlayInfoReponse)));
    // 4.2 通过播放地址播放
    GetVideoPlayAuthRequest getVideoPlayAuthRequest = new GetVideoPlayAuthRequest()
            .setVideoId(uploadVideoId);
    GetVideoPlayAuthResponse getVideoPlayAuthReponse = client.getVideoPlayAuth(getVideoPlayAuthRequest);
    com.aliyun.teaconsole.Client.log(com.aliyun.teautil.Common.toJSONString(TeaModel.buildMap(getVideoPlayAuthReponse)));
