Eclipse STS is reporting I have problem with my spring project.

It's a fresh project generated from the Spring Web MVC Project Template (File->New->Spring Template Project->Spring Web MVC ).

When I create the project it has no problems - it's only once I modify the pom (by adding the hibernate dependencies) that STS then picks up the spring problem.

Strangely if I revert the pom the problem remains.

Also I can run the project on a spring tc server and all works correctly.

Any ideas how I can satisfy this problem report?
