Erro ao rodar o Tomcat7 pelo Maven

Estou dando uma estudada no Spring usado o Maven, ao tentar rodar o Tomcat com o comando mvn tomcat:run dá um erro que não acontece quando eu rodo ele no Tomcat7 configurado no Eclipse.

O erro é esse:

>

Meu pom.xml esta assim:

Alguem sabe o que pode estar errado ??

Imagino que possa ser o javax.servlet, mas tentei algumas alterações mas nada mudou.
