Projeto Web com Maven, Eclipse e libs externas

Estou começando a usar Maven e estou encontrando um probleminha em um projeto que criei no Eclipse, o qual também sou iniciante.
O que acontece é o seguinte:
1° Criei pelo eclipse um projeto maven
2° Transformei esse projeto em um projeto web
3° Adicionei no pom.xml as dependencias (hibernate, jstl, …) e o eclipse criou na arvore um item “Maven Dependencies” com todas elas dentro.
4° Selecionei o servidor Tomcat e mandei rodar

Dai quando o Tomcat roda, pelo eclipse, ele não encontra as classes das bibliotecas adicionadas no pom.xml

Gostaria de saber se tenho que fazer mais alguma coisa.

Alura Git Flow: entenda o que é, como e quando utilizar Entenda o que é Git Flow, como funciona seu fluxo com branches como Master, Develop, Feature, Release e Hotfix, além de vantagens e desvantagens.

Esse é o arquivo Maven que foi gerado pelo Eclipse, o qual inseri as dependências:

Esse é o Log gerado no console do Eclipse. Veja que ele não encontras as classes: org.springframework.web.servlet.DispatcherServlet
Essa classe está presente na dependência: spring-webmvc
