Bom dia!
Estou com problema backend não está rodando.

erro na linha - private Set scores = new HashSet<>();
MENSAGEM: The type Set is not generic; it cannot be parameterized with arguments

erro na linha - private Set getScores() {
return scores;
}

Você está fazendo import de

org.hibernate.mapping.Set

Deveria ser de

java.util.Set
