> In the scheduleTask method of Scheduler class, expression
> forceExternalLocation is useless, since it always evaluates to false:
> !image-2019-04-29-11-16-13-492.png!
> So it can be removed. Moreover, by removing this expression, the code
> structure can be made much simpler, because there are some branches relying
> this expression, which can also be removed.
