I'm trying to use Lombok with Maven and VRaptor on IntelliJ but it doesn't work.

I already read some info in stackoverflow but none solved my problem, i already enabled the Annotation Processor in Intellij but still nothing.

I tryied to compile it from command-line too (Windows) and didn't work.

I also tryed to create another project without maven and add the library, create some classes for test and it works, compile and run perfectly.

Any help?

The project has only 2 class, 1 entity and 1 controller

Here is my pom.xml

Could you be more specific than "it didn't work"? What was the error? – Chastain
I edited my question with more info. – Nonary
the Usuario class has the annotation @Data. And the setNome is generated by it. – Nonary
@Chastain i added more info. – Nonary
I wonder if they made it possible to work with any IDE that is not Eclipse. – Triumvirate
i'l try to same project on eclipse to see if it builds. – Nonary

This should work as is, and has nothing to do with IntelliJ idea. But I would:

  • make sure the @Data annotation is the lombok one
  • remove the repository definition (maven central is fine)
  • use a recent lombok version (1.16.0 as of this writing)
  • rebuild (mvn clean package)

I think the lombok jar is not found by maven in your case or that you might have another @Data.

Thx! Looks like was the version, i didn't see i was using an old version. Shame on me haha. – Nonary
It's more likely to be the repo: browse projectlombok.org/mavenrepo and you'll see it doesn't look like a maven repo. – Avery
mvn clean package and then removing the old war file. Replacing with new one. And then after deployment. Bazinga :D +1 – Hilaryhilbert

This might work

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.6.0</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
                <annotationProcessorPaths>
                    <path>
                        <groupId>org.projectlombok</groupId>
                        <artifactId>lombok</artifactId>
                        <version>1.16.12</version>
                    </path>

Thanks, took me hours and your solution fixed it. Working with maven-compiler-plugin 3.6.2 and lombok 1.16.16 – Pintsize
This works, but unexpectedly moving lombok dependency to the beginning of <dependencies> list also helped. maven-compiler-plugin 3.7.0 lombok 1.18.0 – Sundsvall
According documentation this is for Java 9+ - projectlombok.org/setup/maven – Restrain
Opened my eyes. Thanks when I added another annotation processor (for map struct) lombok stopped working and I was not realising the issue being caused by the now missing implicit declaration of the annotation processor. Took me too many hours ... – Avestan
Same issue as @KevinKussmaul ... it saved me !! – Pullen

You need add lombok plugin:

  <build>
  <plugins>
    <plugin>
      <groupId>org.projectlombok</groupId>
      <artifactId>lombok-maven-plugin</artifactId>
      <version>1.16.8.0</version>
      <executions>
        <execution>
          <phase>generate-sources</phase>
          <goals>
            <goal>delombok</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

no, this is for replacing the Lombok annotations with equivalent source code – Aneto
