Using lombok dependency in my spring-boot project but the getter method yields error at runtime (built successfully though) - spring-boot

Question

I am developing a spring-boot project using Gradle as the build tool on ItelliJ IDE.
I have the dependency of lombok declared in gradle.build:
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-web:2.5.3'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
compileOnly 'org.projectlombok:lombok:1.18.20'
}
I have a model class:
import lombok.Data;
import java.math.BigDecimal;
#Data
public class ProductModel {
private String name;
private BigDecimal price;
private Integer quantity;
}
As you can see I have annotated with #Data.
My controller has the method to handle a POST request, its payload is mapped to the ProductModel:
#PostMapping
public String createProduct(#RequestBody ProductModel productPayload) {
// Runtime error: error: cannot find symbol, 'getName' in 'ProductModel'
productPayload.getName();
}
I know I need to install the lombok plugin on my IntelliJ IDE in order to avoid compiler error on the getter method. So I did that. But when I run my application I get error:
error: cannot find symbol
symbol: method getName()
location: variable productPayload of type CreateProductRestModel
I also tried change the dependency from compileOnly to implementation:
implementation 'org.projectlombok:lombok:1.18.20'
It doesn't help. Why is that? What am I missing?
(I have enabled annotationProcessor on my IntelliJ too)

Answer 1

In order for Gradle to pick up on annotation processors, they have introduced a separate configuration that will generate all the new code ahead of the "normal" compilation.
For Lombok, it would look something like this:
dependencies {
compileOnly 'org.projectlombok:lombok:1.18.20'
annotationProcessor 'org.projectlombok:lombok:1.18.20'
testCompileOnly 'org.projectlombok:lombok:1.18.20'
testAnnotationProcessor 'org.projectlombok:lombok:1.18.20'
}
