Is there a way to create custom annotations in Scala and write a custom annotation processor to verify the annotations?

I have been learning about annotations and what an annotation processor is. I was looking at Java examples and there seems to be a proper way to do it. However, in Scala, I do not get a proper website/documentation to create custom annotations and annotation processor.

If it's not possible in Scala, is there a way to use Java custom annotation processor in Scala classes?

Can someone point me in the right direction?

In Scala there is an option to use compile-time annotations in black-box (type-safe) macros without need to add a compiler extensions or flags.

Here is an example of defining and usage of such annotations for derivation of codecs.
