How to understand in IntelliJ IDEA that background compilation has finished?

Question

Java

In the IntelliJ IDEA settings, I enabled parallel compilation of the project in the background, in Run -> Edit Configurations I disabled Make before launch. As a result, the effect is achieved - the project is compiled in the background.
BUT. There is no way to understand before starting whether the assembly has already ended or not yet. In the event log, for example, information about background compilation does not appear. Do you happen to know if there is a way to hang up at least a call to some Bubuntu notify-send when the background compilation is over?
UPD: On the other hand, if you return Make before Run, it just acts as such a synchronization tool. From the statusbar, you can see that if the classes were recompiled in the background, Make does not touch them. It's just that Helloworld compiles much faster than make runs for me. On a real project should be the rules.

Answer 1

Isn't the status bar at the bottom right showing the execution of all background processes?
