Procura a Caelum, www.caelum.com.br .

Este tipo de problema ocorre por que o maven foi incapaz de baixar as dependências de maneira adequada.
A melhor solução é excluir a pasta repository, dentro de .m2 e, em seguida, executar os comandos

mvn dependency:resolve

E os mvn normais que você usa (clean, package, install)

Beleza irmão. Obrigado. Tentarei aqui.

Só para você ter uma ideia, acabei de ter o mesmo problema.
Tive que excluir tudo da pasta repository e baixar novamente.
Aí, milagrosamente, funcionou.
Eu nunca tive paciência para tentar descobrir se há meios diferentes e menos agressivos para corrigir esse tipo de problema.
