Without more information, we can not help. Maybe is related to your previous problem?
If you can provide the project you're trying to import (or a small one which shows the same problem) it would be very useful.
If you're not able to reproduce the problem, then follow the same steps described for your previous comment:
- Open your Eclipse Error View and Maven Events View.
- Clear both so there's no information from previous actions.
- Reproduce the problem
- Open a new issue with the full eclipse error log and the maven errors on the event view (set the filters on the maven events view to Debug first).
Thanks!
