android - Greenrobot Android Eventbus - 没有选项 eventbusindex 传递给注释处理器

Question

我正在尝试使用 Greenrobot 的 Eventbus 在我的 Android 应用程序中设置一个简单的订阅者，但我遇到了 gradle 构建错误。我在下面显示了我的代码。

事件类

public final class OffersProcessedEvent {}

基础 fragment

public class BaseFragment extends Fragment {
    private boolean registered;

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        EventBus.getDefault().register(this);
        registered = true;
   }

    @Override
    public void onResume() {
        super.onResume();
        if (!registered) {
        EventBus.getDefault().register(this);
        registered = true;
    }
}

    @Override
    public void onPause() {
        super.onPause();
        EventBus.getDefault().unregister(this);
        registered = false;
    }

    public AppCompatActivity getAppCompatActivity() {
        return (AppCompatActivity) getActivity();
    }
}

Activity 帖子'

EventBus.getDefault().post(new OffersProcessedEvent());

订阅码

@Subscribe
    public void onMessageEvent(OffersProcessedEvent event){
        *do whatever*
    }

以下是我的错误

Answer 1

apply plugin: 'kotlin-kapt' // ensure kapt plugin is applied

dependencies {
    implementation 'org.greenrobot:eventbus:3.1.1'
    kapt 'org.greenrobot:eventbus-annotation-processor:3.1.1'
}

kapt {
    arguments {
        arg('eventBusIndex', 'com.example.myapp.MyEventBusIndex')
    }
}
