      pom.xml:

      <!-- lombok mvn dependency -->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.18.24</version>
<scope>provided</scope>

<plugin>
  <groupId>org.kie</groupId>
  <artifactId>kie-maven-plugin</artifactId>
  <version>8.31.1.Final</version>

</plugin>

      sample java code:

      package org.example;
import lombok.Data;
import lombok.Builder;

@Data @Builder
public class Foobar {
  public static void main(String[] args) {
    Foobar.builder().build();
  }
}

      I found that build would fail if I call lombok-generated method in java code. And it's kind of weird because it happens even if I remove the kmodule.xml file.

      Using lombok-generated method in drl is ok.

      Running unit test in Idea with dynamic load model also works well.

      ks.newKieBuilder(kfs).buildAll(ExecutableModelProject.class)

      Error message from kie-maven-plugin: Unable to create KieModule

      Message: The method builder() is undefined for the type Foobar.
