如何解决生成的Mutation类中的错误“方法不会覆盖或实现超类型的方法”？

Question

代码运行正常，但是在我添加行以在Apollo客户端类中实现缓存后，出现此错误，应用无法编译。

当我删除缓存行时，它开始编译并正常工作。我认为我没有正确设置缓存。

我试图使缓存无效并重新启动，并删除生成的文件，以为可以通过重新创建类来解决问题，但是问题仍然存在。

这是客户：

public class MyApolloClient {
private  static final String BASE_URL = "http://192.168.43.33:4444/";
private static ApolloClient apolloClient = null;

public static ApolloClient getApolloClient(Context context) {
    if (apolloClient != null) {
        return apolloClient;
    } else {
        //Directory where cached responses will be stored
        File file = new File(context.getApplicationContext().getCacheDir().toString());
        //Size in bytes of the cache
        int size = 1024 * 1024;
        //Create the http response cache store
        DiskLruHttpCacheStore cacheStore = new DiskLruHttpCacheStore(file, size);
        HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
        loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient okHttpClient = new OkHttpClient.Builder().build();
        apolloClient = ApolloClient.builder().serverUrl(BASE_URL).httpCache(new ApolloHttpCache(cacheStore)).okHttpClient(okHttpClient).build();
        return apolloClient;
    }
}
}

而且，这是唯一使用它的时间：

MyApolloClient.getApolloClient(this).mutate(
        LoginMutation.builder().email(emailEditText.text.toString())
            .password(passwordEditText.text.toString())
            .build()
    ).enqueue(object : ApolloCall.Callback<LoginMutation.Data>() {
        override fun onResponse(response: Response<LoginMutation.Data>) {
            /*val intent = Intent(this@LoginActivity, MainActivity::class.java)
            startActivity(intent)*/
            Log.e("success",response.data().toString())
        }

        override fun onFailure(e: ApolloException) {
            Log.e("failed", e.toString())
        }
    })

谢谢。
