如何使用maven协调lombok和JPAMetalModel处理器

问题描述

如果在maven版本中激活JPAMetaModelEntityProcessor注释处理器，如何使用。

How to use Lombok when JPAMetaModelEntityProcessor annotation processor is activated in the maven build.

Maven config：

Maven config:

[...]
<build>
    <plugins>
        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <compilerArguments>
                    <processor>org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor</processor>
                </compilerArguments>
            </configuration>
        </plugin>
    </plugins>
</build>
<dependencies>
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.hibernate.javax.persistence</groupId>
        <artifactId>hibernate-jpa-2.0-api</artifactId>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-jpamodelgen</artifactId>
        <scope>provided</scope>
    </dependency>
</dependencies>
[...]

在构建过程中（mvn clean install），MetaModel对象生成正确，但似乎Lombok Annotation处理器不再添加到Javac编译中。所有@Getter，@ Setter，......都不起作用。

During the build process (mvn clean install), MetaModel objects are generated correctly but it seems the Lombok Annotation processor is not added into the Javac compilation anymore. All @Getter, @Setter,... doesn't work.

推荐答案

在查看lombok项目后，我找到了一个解决方案。

After a look into the lombok project I found a solution.

当将JPAMetaModelEntityProcessor指定为javac注释处理器时，似乎删除了lombok处理器。

When specifying the JPAMetaModelEntityProcessor as javac annotation processor, the lombok processor seems to be removed.

To更正这一点，我们可以简单地在maven-compiler-plugin中添加Lombok注释处理器：

To correct this, we can simply add the Lombok annotation processor in the maven-compiler-plugin:

[...]
<plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
        <compilerArguments>
            <processor>org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor,lombok.launch.AnnotationProcessorHider$AnnotationProcessor</processor>
        </compilerArguments>
    </configuration>
</plugin>
[...]
