Jars not copied to Tomcat's lib folder

I am doing some basic spring stuff and stuck at some point. I am getting ClassNotFoundException whenever I deploy my application on Tomcat.

I observed that the jars are not copied to Tomcats lib folder. When I copied the jars manually to Tomcats lib folder it works fine.

Please let me know if I am making any blunder.

PS - I am using Spring tool suite 2.6.0,Tomcat 6 and its a Maven project.

Thanks.
