Error when wrong annotation is used in wrong context (eg: @EventSourcingHandler) #75
Description
Feature Description
Error when wrong annotation is used in wrong context (eg: @EventSourcingHandler).
For example:
- EventSourcingHandler should only be added to classes that are aggregates.
- SagaEventHandler for sagas
This is extra: annotating same method with EventSourcingHandler, SagaEventHandler, CommandHandler does not give error.
Talked about it in AxonFramework/AxonFramework#1755
Current Behaviour
No errors or warnings.
For SagaEventHandler annotation, the plugin will consider the method as a potential receiver of the payload but it should not.
Wanted Behaviour
Show an error when annotation is not put on correct context (methods, etc).
Possible Workarounds
Extra
Most devs uses Intellij IDEA but would be great if could also work on a Maven plugin with java agent or other (maybe also gradle but I prefer maven).
And with a plugin, there could be checks done in CI, etc.
