After upgrading from Java 11 to Java 17, I'm encountering compilation errors related to Lombok's @FieldNameConstants annotation. I'm also using MapStruct, so I'm mentioning that in case that could be related to their annotation processors somehow.

Error

error: cannot find symbol
import static com.example.dto.ContactRegistration.Fields.contactGuid;
                                                 ^
  symbol:   class Fields
  location: class ContactRegistration

Environment

• Java Version: 17
• Lombok Version: 1.18.34
• MapStruct Version: 1.6.3
• MapStruct Binding Version: 0.2.0
• Build Tool: Gradle 7.6

Gradle Configuration

lombokVersion = '1.18.34'
mapstructVersion = '1.6.3'
mapstructBindingVersion = '0.2.0'

dependencies {
    implementation("org.mapstruct:mapstruct:${mapstructVersion}")
    implementation("org.projectlombok:lombok:${lombokVersion}")
    
    annotationProcessor "org.projectlombok:lombok:${lombokVersion}"
    annotationProcessor "org.mapstruct:mapstruct-processor:${mapstructVersion}"
    annotationProcessor "org.projectlombok:lombok-mapstruct-binding:${mapstructBindingVersion}"
}

Auto-generated DTO (from OpenAPI/YAML)

The DTOs are generated from a YAML specification with Lombok imports:

x-imports:
  - lombok.experimental.FieldNameConstants

Resulting generated class:

import lombok.experimental.FieldNameConstants;
import com.fasterxml.jackson.annotation.JsonInclude;
import jakarta.validation.constraints.Size;
import jakarta.validation.constraints.Pattern;
import jakarta.validation.Valid;

@FieldNameConstants
@JsonInclude(JsonInclude.Include.NON_NULL)
public final class ContactRegistration extends org.springframework.hateoas.RepresentationModel {
    
    @Pattern(regexp = ".*\\S.*", message = "PATTERN_INVALID")
    @Size(min = 1, max = 100)
    private String firstName;
    
    @Valid
    private Address address;
    
    @Size(min = 1, max = 100)
    private String contactGuid;
    
    // Getters and setters omitted for brevity
}

Question

Since the DTOs are auto-generated from OpenAPI/YAML files, I cannot manually add the Fields class. The error only appeared after upgrading to Java 17.

What configuration changes are needed to make Lombok's @FieldNameConstants work properly with Java 17 and MapStruct?

Is this a known issue with the annotation processor ordering or Java 17 compatibility?

Thank you.
