eclipse spring boot starter project gives errors

I was trying to check out the starter project for spring boot provided in Eclipse (version Mars.2) but I get errors.

This is what I do:

  1. Import new spring getting started content: enter image description here

  2. Selecting spring boot gives me two new projects:

enter image description here

  1. Running gs-spring-boot-complete gives me this error

`

  1. Googling this error leads me to maven repository, so I import ch.qos.logback

  2. Running again (Run As... -> Spring Boot App) gives me this error:

You either need to specify explicitly a bean validator:

@Bean
public Validator validator(){
   return new org.springframework.validation.beanvalidation.LocalValidatorFactoryBean();
}

or add this to your pom.xml:

<dependency>
    <groupId>com.fasterxml</groupId>
    <artifactId>classmate</artifactId>
    <version>0.8.0</version>
</dependency>
