I am registering event bus in oncreate method: EventBus.getDefault().register(this);

I am subscribing more than 1 events in MainActivity like:

@Subscribe(threadMode = ThreadMode.MAIN)
    public void onMessageUpdatingEvent(MessageUpdatingEvent event) {
       //code
    }

@Subscribe(threadMode = ThreadMode.MAIN)
    public void onMessageUpdatedEvent(MessageUpdatedEvent event) {
        //code
    }

Check that you do not have multiple versions of EventBus added to your project. The priority property of @Subscribe was added with EventBus 3.0.0, make sure all of your code and libraries use the same version to compile.

Got the same error, how to solve it?

Not have multiple versions of EventBus added to my project, only version 3.1.1.

#原来是第三方jar库引起，也不是EventBus版本冲突，具体原因未知（似乎跟jar编译的jdk版本有关），待查。

maybe ur third part lib also have the annotation called @Subscribe and eventbus get the wrong annotation which don't have the priority value
