Right now AA skips the generation of all the Enhanced Classes when there was a validation error in any place in the project. This causes a huge list of errors to be displayed and it is almost impossible to find the error that is causing the problem

A good option, would be to generate all the classes, except the one causing the error... This would be the simplest solution.

Even though, in most of the scenarios would be useful even generate the class with the validation error as described here, but this would require probably a revision of every annotation handler in the framework.
