Answer 1

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>

Answer 2

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>

Answer 3

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>
