Retrofit usage in with API in Java

According to information from official site I added latest depedency and started to develop.

First I created model with data I'm interested:

public class Data{
    String parametr1;
    //geters and setters ommited
}

second step was to add service:

public interface GitHubService {
    @GET("/repos/{owner}/{repo}")
    Call<Data> repoInfos(@Path("user") String owner, @Path("repo") String repo);

    Retrofit retrofit = new Retrofit.Builder().baseUrl("https://api.github.com/").build();
}

Third one was to add implementation:

@Service
public class GitHubServiceImpl implements GitHubService {

    final GitHubService gitHubService = GitHubService.retrofit.create(GitHubService.class);

    @Override
    public Call<DetailDto> repoDetails(String owner, String repo) {
        return gitHubService.repoDetails(owner, repo);
    }
}

But there is an error:

java.lang.IllegalArgumentException: Could not locate ResponseBody converter for class model.Data.

Here is full error log trace

For maven dependency:

<dependency>
    <groupId>com.squareup.retrofit2</groupId>
    <artifactId>converter-gson</artifactId>
    <version><latest-version></version>
</dependency>

For code add a ConverterFactory:

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl(Constants.API_BASE_URL)
        .addConverterFactory(GsonConverterFactory.create())
        .build();

This should do it.
