Dependência devtools não restarta o servidor automaticamente

Fiz o import e não funciona. Olhei num tópico aberto e o instrutor pedia para excluir a pasta spring-boot-devtools da pasta C:\Users\diego.m2\repository\org\springframework\boot

Fiz isso, e importei com o Maven, não deu certo. Estou usando Eclipse.

Segue o meu pom.xml
