How to configure Lombok with maven-compiler-plugin?

O.Zaiats picture O.Zaiats · Feb 15, 2017 · Viewed 29k times · Source

I have a root module and submodule in maven in the project. I am trying to use Lombok. I have added

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.16.12</version>
    <scope>provided</scope>
</dependency>

to root pom.xml. In submodule I have a class with Lombok annotations. When I am trying to build the project I get a lot of

cannot find symbol

where I am trying to call getters and setters.

I have tried to use lombok-maven-plugin with same version (1.16.12) in root pom and in the sub pom as well with delombok and moving my annotated class to src/main/lombok, I have looked through almost all questions in SO, try all the variants, but not succeed.

I am using Maven 3, Java 8, maven-compiler-plugin with 3.6.1 version.

How should I configure the project to be able to use lombok? Or maybe I am doing smth wrong.

This is not a direct answer to the question which seems to be solved but acts as reference for future searchers:

If you're using Dagger (or something else) to process your annotations like

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.7.0</version>
      <configuration>
        <annotationProcessorPaths>
          <path>
            <groupId>com.google.dagger</groupId>
            <artifactId>dagger-compiler</artifactId>
            <version>2.15</version>
          </path>
        </annotationProcessorPaths>
        <source>1.8</source>
        <target>1.8</target>
      </configuration>
    </plugin>
    ....
  </plugins>
</build>

You have to add lombok as path like

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.7.0</version>
      <configuration>
        <annotationProcessorPaths>
          <path>
            <groupId>com.google.dagger</groupId>
            <artifactId>dagger-compiler</artifactId>
            <version>2.15</version>
          </path>

          <!-- SOLUTION --> 
          <path>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.16.20</version>
          </path>


        </annotationProcessorPaths>
        <source>1.8</source>
        <target>1.8</target>
      </configuration>
    </plugin>
    ....
  </plugins>
</build>

You still have to list lombok as provided dependency tho.
