erro ao rodar com Banco h2

Oi Givanildo,

Acredito que deve ter sido algum problema com o Maven quando ele foi baixar as dependências do projeto.

Faz o seguinte então, apague o diretório .m2 do maven(é uma pasta oculta que fica localizada no diretório do seu usuário no computador), depois no Eclipse clique o botão direito do mouse no projeto e escolha a opção Maven -> Update Project.

Veja se funciona depois disso.

Ocorreu o mesmo erro
