m2eclipse error

Question

I am developing a web application with Eclipse and I generate the project with a maven archetype.

When I enable maven dependency management, Eclipse mark some errors

Answer 1

This what helped me:

1. Delete the project from eclipse (but don't delete from disk)
2. Close eclipse
3. In your user folder there is .m folder. Delete repository folder underneath it (.m/repository).
4. Open eclipse
5. Import project as existing maven project (from disk).

Good luck.
