Модернизация 2.0 / Джексон: исключение UnrecognizedPropertyException

Я пытаюсь использовать Retrofit 2.0 с парсером Джексона, но это не работает. Он не отображает значения в модели. Это дает мне исключение:

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: нераспознанное поле «total_count» (класс models.GitResult), не отмеченное как игнорируемое (3 известных свойства: «incompleteResults», «items», «totalcount»])
при [Источник: буфер ((буфер (okio.GzipSource@2235992))). InputStream (); строка: 1, столбец: 21] (через цепочку ссылок: models.GitResult ["total_count"])

Но ключевое значение в моей модели и в ответе json совпадает. Это модель:

private boolean incompleteResults;
private List<Item> items = new ArrayList<Item>();
private int totalcount;

ответ json это

Модель предмета также сделана правильно. Он работает с GsonConverterFactory, но не работает с JacksonFactory.

Вот моя настройка клиента:

private static GitApiInterface gitApiInterface ;
    private static String baseUrl = "https://api.github.com" ;

    public static GitApiInterface getClient() {
        if (gitApiInterface == null) {

            OkHttpClient okClient = new OkHttpClient();
            okClient.interceptors().add(new Interceptor() {
                @Override
                public Response intercept(Chain chain) throws IOException {
                    Response response = chain.proceed(chain.request());
                    return response;
                }
            });

            Retrofit client = new Retrofit.Builder()
                    .baseUrl(baseUrl)
                    .client(okClient)
                    .addConverterFactory(rest.JacksonConverterFactory.create())
                    .build();
            gitApiInterface = client.create(GitApiInterface.class);
        }
        return gitApiInterface ;
    }

и мои зависимости от Gradle

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.2.1'
    compile 'com.squareup.retrofit:retrofit:2.0.0-beta4'
