I know this question before, BUT when the questioned was asked, it was years ago, and the fix then might not be the fix now. Believe me when I tell you I did my research on this before coming here.
I have the latest IntelliJ installed '2024.1.7', I have the Lombok Plugin installed in IntelliJ, and I updated my pom.xml to include the version of Lombok (1.18.36) for the dependency. I also have the Annotation Processing turned on for the build process. All these I have seen from previous posts, so I wonder what could be going wrong.

This application ran perfectly with Lombok under Eclipse and STS. This application uses the maven: mvn clean install -U and runs perfectly. The app builds in IntelliJ with Lombok, and all the tests run. Now I want to run this Spring Boot app in IntelliJ and I get 6 errors that all stem from not being able to find the getters or setters.

java: cannot find symbol
symbol:   method setCompanyId(java.lang.Long)
location: variable company of type com.product.htmx.demo.model.CompanyEntity

CompanyEntity is defined as follows:

@Data
@With
@NoArgsConstructor
@AllArgsConstructor
@SuppressWarnings("serial")
@Entity
@Table(name = "company")
public class CompanyEntity implements Serializable {
    // `company_id` int NOT NULL AUTO_INCREMENT,
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "company_id")
    private Long companyId;

I get the same error "cannot find symbol" with 5 other classes. However, the other entities and DTO's have multiple properties, and yet I don't get the same error message. I know this might seem like a duplicate message, but I know this is not the same fix as the other much older messages.

• Are you using JDK 23 to run the application with IntelliJ by any chance? If so, please see Build Failure: @Data Annotation won't regonize by Maven Specifically, please check the part about <proc>full</proc>. – dan1st Commented Mar 15 at 22:59
• @dan1st Your answer didn't work for me, so I posted my answer which worked for me somehow. – Remzi Cavdar Commented Mar 15 at 23:47
• I did have JDK 23 installed even though on Windows 11 I set up the environmental values for JDK 21. I removed JDK 23 altogether to avoid any confusion. So, far this did not remove the issue. – tjholmes66 Commented Mar 15 at 23:58

What worked for me is to put the following into Build in my pom.xml:
