A missing profile is only notified at the end of a run.
Since this may mean that the run is useless, it would be helpful if:
1) It was also noted near the start, so the user could cancel the run.
It's still helpful at the end, as it saves scrolling back to see if there was a problem.
2) There were an option to fail a run if a profile is not found. This option should be settable in a POM and in settings.xml
