How to put two actors on the same schedule?

Hi,

I have a scheduleconfigured that's named "EveryMinuteDuringWeekdays". I want two distinct actors to receive a Tick-message on that named schedule. If I schedule the ticket message for only one actor, it works fine. If I want to schedule it for the other actor as well, I get an exception.

Exception:
org.quartz.ObjectAlreadyExistsException: Unable to store Job : 'DEFAULT.EveryMinuteDuringWeekdays_Job', because one already exists with this identification.

Code:
val scheduler = QuartzSchedulerExtension(system = context.system) scheduler.schedule("EveryMinuteDuringWeekdays", self, Tick) scheduler.schedule("EveryMinuteDuringWeekdays", receiver, Tick)

Looking at the source of akka-quartz-scheduler I cannot seem to find the correct way on how I'd make sure that more than one actor can be on a schedule. Could you point me to the right direction?

It looks like this exception is coming from Quartz itself because that job name is already registered. Here's two options:

  1. Register the same schedule twice under two different names.
  2. When scheduling the job, point to a broadcast actor / pool that simply broadcasts the message to any actors that should receive the message. You can find more on broadcasting here.

Does that help?
