我尝试使用自动值设置一个不可变列表。我遵循了官方的用户指南，该指南建议实施类似的方法：

@AutoValue
public abstract class ListExample {
  public static ListExample create(String[] mutableNames) {
    return new AutoValue_ListExample(ImmutableList.copyOf(mutableNames));
  }

  public abstract ImmutableList<String> names();
}

我的实现是下一个：

@AutoValue
public abstract class MovieList {

    @SerializedName("results")
    //if a change ImmutableList to simple List right below
    //the Retrofit call works and my Object is printed.
    public abstract ImmutableList<Movie> movies();

    public static TypeAdapter<MovieList> typeAdapter(Gson gson) {
        return new AutoValue_MovieList.GsonTypeAdapter(gson);
    }
}

我想遍历作为改造调用响应的 MovieList 对象的电影。

movieService.getPopularMovies().enqueue(new Callback<MovieList>() {
                @Override
                public void onResponse(Call<MovieList> call, Response<MovieList> response) {
                    if(response.isSuccessful()){

                        for(Movie m: response.body().movies()){
                            Timber.e(m.originalTitle());
                        }
                    }
                }

                @Override
                public void onFailure(Call<MovieList> call, Throwable t) {
                    Timber.e(t.toString());
                }
            });

上面的改造调用会导致以下堆栈跟踪：

如果在上面的 MovieList 抽象类中将 ImmutableList 更改为简单 List，则 Retrofit 调用将起作用并且我的 Object 将被打印。是否需要添加一些依赖项？我的 ImmutableList 从com.google.common.collect.ImmutableList现在导入。

我应该如何设置 ImmutableList 依赖项以便能够遍历 MovieList 对象？
