If an Exception is thrown during the generation of the DSL output by my org.eclipse.xtext.generator.IGenerator
I would like to present it - or an appropriate message - to the user.

Is there an build in way to do that?

No, you'd have to override the BuilderParticipant of your language for
that purpose. Note that this is not very eclipsish as the builder runs
in a background job and a dialog would appear as out of nowhere.

The usual best practice is to cover all such conditions during
validation, thus given early feedback on invalid models already during
editing and prevent the generator from running in these cases.
