无法使用lombok构建maven jhipster项目

Question

./mvnw和mvn clean install在添加lombok依赖项时失败，但从Intellij IDE启动时成功运行。发现以下错误：

INFO] -------------------------------------------------------------
[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] src/main/java/web/rest/core/service/impl/ProductServiceImpl.java:[18,29] cannot find symbol
  symbol:   method builder()
  location: class com.test.one.web.rest.core.model.Product

这是POJO

import lombok.Builder;
import lombok.Data;

@Data
@Builder
public class Product {
    private String name;
}

Answer 1

Jhipster生成的maven项目使用maven compile插件中的annotationProcessorPaths，这就是为什么它不能查找最新的lombok的原因，除非我们将lombok指定为注释处理器之一。

工作代码如下所示。

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>${maven-compiler-plugin.version}</version>
<configuration>
    <annotationProcessorPaths>
        <path>
            <groupId>org.mapstruct</groupId>
            <artifactId>mapstruct-processor</artifactId>
            <version>${mapstruct.version}</version>
        </path>
        <!-- For JPA static metamodel generation -->
        <path>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-jpamodelgen</artifactId>
            <version>${hibernate.version}</version>
        </path>
        <path>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.16.18</version>
        </path>
    </annotationProcessorPaths>
</configuration>
