Lombok @Builder "cannot find symbol" error with Maven & IntelliJ

Hey everyone, I'm facing a frustrating issue with Project Lombok and could use some help. I'm working on a Spring Boot project using IntelliJ IDEA and Maven, and I'm getting a java: cannot find symbol error for the builder() method. The error occurs in my test class ShutterResponseDTOTest.java when I try to instantiate a DTO using the builder pattern. Here are the relevant code snippets and the full error message. What I've already checked and done: I've correctly added the Lombok dependency to my pom.xml. I’ve confirmed that “Enable annotation processing” is checked in my IntelliJ IDEA settings (Settings > Build, Execution, Deployment > Compiler > Annotation Processors). I also tried using the <optional>true tag for the dependency, but that didn't work either, so I reverted to provided. I have the Lombok plugin installed in IntelliJ.

Have you tried explictly rebuilding your project? Also <optional>true</optional> is something which is relevant when resolving transitive dependencies. I think what you are looking for is <scope>compile</scope> but this is already the default.

yeah rebuilding using idea button and than also ./mvnw test

kyrylomalyiOP•7d ago

Do you have the annotation processor set up in the configuration of your <build> plugins in the pom.xml?
