Segui todos os passos do instrutor no projeto listavip, porém quando vou rodar o projeto, (Run as Java Application) está gerando o seguinte erro:

Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/context/ApplicationContext
    at br.com.alura.listavip.Configuracao.main(Configuracao.java:10)
Caused by: java.lang.ClassNotFoundException: org.springframework.context.ApplicationContext

Minha classe Configuração.java

package br.com.alura.listavip;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Configuracao {

    public static void main(String[] args) {
        SpringApplication.run(Configuracao.class, args);
    }
}

Meu pom.xml
