Eclipse IDE 2023-09: NullPointerException when Trying to Use Lombok with Spring Boot
I'm experimenting with I'm stuck on something that should probably be simple. Can someone help me understand I'm working with a frustrating scenario while trying to use Lombok with my Spring Boot application in Eclipse IDE 2023-09. I have the Lombok library correctly added to my Maven dependencies, but whenever I attempt to run my application, I encounter a `NullPointerException` that seems to originate from a field that I expected Lombok to initialize. Here’s the relevant part of my `UserService` class: ```java import lombok.AllArgsConstructor; import lombok.Getter; import org.springframework.stereotype.Service; @Service @AllArgsConstructor @Getter public class UserService { private final UserRepository userRepository; public User getUser(Long id) { return userRepository.findById(id).orElseThrow(() -> new RuntimeException("User not found")); } } ``` In my `UserController`, when I try to call `userService.getUser(1L)`, I get the following stack trace: ``` Exception in thread "main" java.lang.NullPointerException at com.example.service.UserService.getUser(UserService.java:15) at com.example.controller.UserController.getUser(UserController.java:10) ``` I've double-checked that I have the Lombok plugin installed in Eclipse and that it’s enabled. I've also tried cleaning the project and rebuilding it, but the question continues. I suspect that Lombok's annotations are not being processed correctly. I also checked my `pom.xml` for the Lombok dependency: ```xml <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.24</version> <scope>provided</scope> </dependency> ``` When I move the field initialization to a constructor without Lombok, everything works as expected. Does anyone have insights on how to resolve this? Is there something specific I might be missing with Lombok’s integration in Eclipse? Is there a better approach? Cheers for any assistance! Has anyone else encountered this? Hoping someone can shed some light on this. This is for a desktop app running on Ubuntu 22.04. Any help would be greatly appreciated!
