How to generate FeignClient interfaces and Lombok-annotated models using OpenAPI Generator?

I am using openapi-generator-maven-plugin to generate Feign clients and models from an OpenAPI spec.
Example OpenAPI file:

openapi: 3.0.1
info:
  title: ReviewApis
  version: 1.0.0
paths:
  /create-new-review:
    post:
      summary: Create a new review
      operationId: createNewReview
      ...
components:
  schemas:
    Review:
      type: object
      required: [title, content, score, bookId]
      properties:
        id:
          type: string
          format: uuid

Maven plugin config:

<plugin>
  <groupId>org.openapitools</groupId>
  <artifactId>openapi-generator-maven-plugin</artifactId>
  <version>7.3.0</version>
  <executions>
    <execution>
      <id>generate-review-service-feign-client</id>
      <goals><goal>generate</goal></goals>
      <configuration>
        <inputSpec>${project.basedir}/src/main/resources/review-service/review-service.yaml</inputSpec>
        <generatorName>spring</generatorName>
        <library>spring-cloud</library>
        <apiPackage>com.book_reviewers.feign.review_service.api</apiPackage>
        <modelPackage>com.book_reviewers.feign.review_service.model</modelPackage>
        <configOptions>
          <interfaceOnly>true</interfaceOnly>
          <useFeignClientUrl>true</useFeignClientUrl>
          <apiNameSuffix>Api</apiNameSuffix>
        </configOptions>
      </configuration>
    </execution>
  </executions>
</plugin>

The FeignClient interfaces are generated correctly, but the models do not have Lombok annotations (@Data, @Builder, etc.).

I found this Baeldung article, but it doesn't cover FeignClient generation.

How can I generate both:

• FeignClient interfaces; and
• Lombok-annotated models

using OpenAPI Generator?

I tried:

      <configOptions>
        <interfaceOnly>true</interfaceOnly>
        <useFeignClientUrl>true</useFeignClientUrl>
        <apiNameSuffix>Api</apiNameSuffix>
        <useLombok>true</useLombok>
        <useDataAnnotation>true</useDataAnnotation>
        <useBuilderAnnotation>true</useBuilderAnnotation>
        <useAllArgsConstructorAnnotation>true</useAllArgsConstructorAnnotation>
        <useNoArgsConstructorAnnotation>true</useNoArgsConstructorAnnotation>
      </configOptions>

But it didn't help either.

I tried to generate FeignClient and models in separate executions:

      <!-- Generate FeignClient interface for Review-Service -->
      <execution>
        <id>generate-review-service-feign-client</id>
        <goals><goal>generate</goal></goals>
        <configuration>
          <inputSpec>${project.basedir}/src/main/resources/review-service/review-service.yaml</inputSpec>
          <generatorName>spring</generatorName>
          <library>spring-cloud</library>
          <apiPackage>com.book_reviewers.feign.review_service.api</apiPackage>
          <modelPackage>com.book_reviewers.feign.review_service.model</modelPackage>
          <configOptions>
            <interfaceOnly>true</interfaceOnly>
            <useFeignClientUrl>true</useFeignClientUrl>
            <apiNameSuffix>Api</apiNameSuffix>
          </configOptions>
        </configuration>
      </execution>
      <execution>
        <id>generate-review-service-models</id>
        <goals><goal>generate</goal></goals>
        <configuration>
          <inputSpec>${project.basedir}/src/main/resources/review-service/review-service.yaml</inputSpec>
          <generatorName>java</generatorName> <modelPackage>com.book_reviewers.feign.review_service.model</modelPackage>
          <configOptions>
            <useLombok>true</useLombok>
            <useDataAnnotation>true</useDataAnnotation>
            <useBuilderAnnotation>true</useBuilderAnnotation>
            <useAllArgsConstructorAnnotation>true</useAllArgsConstructorAnnotation>
            <useNoArgsConstructorAnnotation>true</useNoArgsConstructorAnnotation>
            <generateApiClasses>false</generateApiClasses> <generateSupportingFiles>false</generateSupportingFiles>
          </configOptions>
        </configuration>
      </execution>
    </executions>
  </plugin>

But I get the error:

package okhttp3.logging does not exist

You can use spring generator for both model and interfaces.
Here I had provided updated build plugins for your reference.

            </executions>
        </plugin>
    </plugins>
</build>

I had added two additional properties for Lombok enablement and Lombok annotations which will going to use.

Below property will inform generator that Lombok is enable for this build command.

 <useLombokAnnotations>true</useLombokAnnotations>

Below property will tell generator that these Lombok annotations i want to use on my generated sources.
You can find detailed explanation for same using below additionalModelTypeAnnotations

<additionalModelTypeAnnotations>
    @lombok.Data 
    @lombok.NoArgsConstructor
    @lombok.AllArgsConstructor
</additionalModelTypeAnnotations>
                            

And here is the sample generated source for Review.java class.
