Oi Gabriel, tudo bem?
Qual curso você está fazendo?
Mas de cara, será que não seria legal tentar usar a versão 8 do Tomcat? A versão 9 ainda não é final... Testa com a mais recente da 8, pf?
https://tomcat.apache.org/download-80.cgi
Abraços!
Ja finalizei os cursos de jsf, os 3. Porém este erro ocorre até mesmo nas versões anteriores.
Além da mensagem indicando que não consegue iniciar o tomcat, tem mais informações sobre o erro no console? Pode colar aqui?

Essa mensagem me chamou atenção:
java.lang.ClassNotFoundException: org.apache.commons.fileupload.FileItemFactoryAlguém está querendo usar essa classe e não está encontrando. Meu chute inicial é adicionar o commons-fileupload no projeto.
