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

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.
After a look into the lombok project I found a solution.
When specifying the JPAMetaModelEntityProcessor as javac annotation processor, the lombok processor seems to be removed.
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$AnnotationProcessor</processor>
</compilerArguments>
</configuration>
</plugin>
[...]
The solution of @Pierrick is right. but I can offer this solution. because we can add many processors with this.
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<annotationProcessorPaths>
<path>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>${lombok.version}</version>
</path>
<path>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-jpamodelgen</artifactId>
<version>5.4.1.Final</version>
</path>
</annotationProcessorPaths>
</configuration>
</plugin>
The Solution if @Pierrick is not totally correct. You have to switch the order of the processors.
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<compilerArguments>
<processor>
lombok.launch.AnnotationProcessorHider$AnnotationProcessor,org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor
</processor>
</compilerArguments>
</configuration>
</plugin>
