I want to add Lombok to my Spring project. I'm using I use Maven, so I put the lombok dependency on my pom.xml file.
Here is the dependency part of my pom.xml file:

What is your parent pom? – Andriy Slobodyanyk
You can try putting maven into debug to see if it prints out any more info. Add the command line option -X. Have you installed the Lombok IntelliJ plugin? – Michael
To see the full stack trace of the errors, re-run Maven with the -e switch. can you re run and show the stacktrace. – mavriksc
The failure shows that it is not a problem of lombok your problem is Spring Boot...cause you wrote Spring project but the dependencies shows you are using spring boot ? – khmarbaise
please add the full POM. Esp the plugin section. – Darren Forsythe

Look carefully at this line

[WARNING] No processor claimed any of these annotations: org.springframework.web.bind.annotation.PathVariable,org.springframework.beans.factory.annotation.Autowired,org.springframework.web.bind.annotation.RequestMapping,org.springframework.stereotype.Controller,org.springframework.web.bind.annotation.RequestBody,javax.persistence.Table,org.springframework.stereotype.Service,com.fasterxml.jackson.annotation.JsonIgnore,javax.persistence.Enumerated,org.springframework.web.bind.annotation.ExceptionHandler,org.springframework.stereotype.Repository,javax.persistence.ManyToMany,javax.persistence.Id,org.springframework.web.bind.annotation.ControllerAdvice,javax.persistence.Entity,javax.persistence.ManyToOne,com.fasterxml.jackson.annotation.JsonBackReference,org.springframework.boot.autoconfigure.SpringBootApplication,javax.transaction.Transactional,javax.persistence.JoinColumn,javax.persistence.OneToMany,org.springframework.web.bind.annotation.RestController,javax.persistence.OneToOne,javax.persistence.Column,org.springframework.stereotype.Component,javax.persistence.GeneratedValue,javax.persistence.Transient,javax.annotation.PostConstruct,org.springframework.web.bind.annotation.RequestHeader,com.fasterxml.jackson.annotation.JsonManagedReference

You need more starters to your pom.xml

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>

As you can see, Lombok is declared as a optional dependency, with no scope or version. The parent pom is the Spring boot parent one. The parent pom contains all settings for handling Lombok.
