I got the same problem and this is how i solved. :
Right click your project, choose Run As -> Maven install.
Observe the output console to see the installation progress. After
the installation is finished, you can continue to the next step.
Right click your Spring MVC project, choose Maven -> Update Project.
Choose your project and click OK. Wait until update process is
finished.
The error still yet, then do Project->Clean and then be sure you have selected our project directory and then do the follow Project->Build.
