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.
