Question

我想将Lombok添加到我的Spring项目中。我使用Maven，所以我把lombok依赖放在我的pom.xml文件上这是我的pom.xml文件的依赖部分：

arrays

当我尝试使用＆＃34; mvn clean install＆＃34;运行maven时，构建失败，我找不到原因。这是日志：

我使用IntelliJ并且已经检查过＆＃34;启用注释处理＆＃34; （首选项 - ＆gt;构建，执行，部署 - ＆gt;编译器 - ＆gt;注释处理器）。

当我运行mvn clean install -e：

仔细看看这一行

[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

你的pom.xml需要更多的启动器

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

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

等

如您所见，Lombok被声明为可选依赖项，没有范围或版本。父pom是Spring引导父级的。父pom包含处理Lombok的所有设置。

我在Spring项目中使用Lombok，但Maven构建失败
