Class is not imported although it is already present in the project libraries (by using maven)

I have created a maven project.

I've tried to use a class that is already imported in my libraries (since I declare it in the pom.xml) but IntelliJ Idea 13 Ultimate is not auto-importing it.

When I press the red bulb and ask it to import a maven dependency it finds the class in the previous version of the current library.

Here is my pom.xml file :
