        This also use the javax.servlet package. Do I need to add another dependency?

@Mugibor you should upgrade at least to 3.0.46 to have the jakarta option supported.

<plugin>
  <groupId>io.swagger.codegen.v3</groupId>
  <artifactId>swagger-codegen-maven-plugin</artifactId>
  <version>3.0.46</version>
  ...
</plugin>

Thx, one more question. I'm using currently the 3.0.54 version. While the application running I got an error with the following:
Swagger2SpringBoot class :
java: cannot find symbol
symbol: class WebMvcConfigurerAdapter
location: package org.springframework.web.servlet.config.annotation

Currently I'm migrating from 2.7 to 3.2.3. What should I change to work this java codegen with spring boot v3?

[tgillain]

It looks like this is the issue you are facing https://www.baeldung.com/web-mvc-configurer-adapter-deprecated

[Mugibor]

`import org.springframework.context.annotation.Configuration;
import org.springframework.format.FormatterRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

@SpringBootApplication
@componentscan(basePackages = { "io.swagger", "XX" , "io.swagger.configuration"})
public class Swagger2SpringBoot implements CommandLineRunner {`

I'm not sure of that, this class has the error "cannot find symbol"
