Esse erro => java.util.zip.ZipException: invalid LOC header (bad signature) indica que alguma dependência do seu projeto foi baixada corrompida... acho que o jeito mais fácil é dar um mvn clean no projeto e baixar tudo de novo.

Eu Removi todas as dependências e mesmo assim não foi, tem o link onde posso baixar o projeto da aula 1 completo?

Acho que não tem o projeto pronto.. vc apagou a pasta .m2? ela fica na pasta do seu usuário.
