YouTube API返回401 Unauthorized之前工作过

Question

我的完整错误：

  

＆＃34;例外com.google.api.client.googleapis.json.GoogleJsonResponseException：401未经授权＆＃34;

以下是我的Gradle代码示例：

HttpTransport httpTransport = new NetHttpTransport();
            JsonFactory jsonFactory = new JacksonFactory();
            GoogleCredential credential = new GoogleCredential.Builder()
                    .setTransport(httpTransport)
                    .setJsonFactory(jsonFactory)
                    .setClientSecrets(clientId, clientSecret).build();
            credential.setAccessToken(videoDetails.accessToken);
            youtube = new YouTube.Builder(httpTransport, jsonFactory, credential).setApplicationName(
                    "My_Videos").build();

            System.out.println(":::uploadind videos on youtube");
            Video videoObjectDefiningMetadata = new Video();
            setSnippets(videoDetails, videoObjectDefiningMetadata)
            InputStreamContent mediaContent = new InputStreamContent(VIDEO_FILE_FORMAT, new BufferedInputStream(new FileInputStream("/home/Desktop/uploadedVideos/146354902123990438f03164744e5a43f635081ba48dc.mp4")));
            YouTube.Videos.Insert videoInsert = youtube.videos().insert("snippet,statistics,status", videoObjectDefiningMetadata, mediaContent);
            MediaHttpUploader uploader = videoInsert.getMediaHttpUploader();
            uploader.setDirectUploadEnabled(false);
            Video returnedVideo = videoInsert.execute();
            res.put("Id", returnedVideo.getId())
            res.put("Tittle",returnedVideo.getSnippet().getTitle())
            res.put("isSuccess", true)
            println res

此代码工作时间为六个月，但现在它给了我例外。请帮助。
