Upgrade to openAPI not compiling

We are doing a major upgrade from jave 8 to java 21 so we are having to upgrade many things all at once.

I am getting this crazy compiler error, I am running mvn compile and getting this error message.

[ERROR] /C:/dev/workspaces/.../src/main/java/com/.../config/SwaggerConfig.java:[13,49] cannot find symbol
[ERROR]   symbol:   class builder
[ERROR]   location: class org.springdoc.core.models.GroupedOpenApi

import org.springdoc.core.models.GroupedOpenApi;
import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

@Configuration
public class SwaggerConfig {

    @Bean
    public GroupedOpenApi  api() {
        GroupedOpenApi api =  new GroupedOpenApi.builder()
          .pathsToMatch("/path/**")   
                .build()
          ;                                           
    }

}

I have these dependencies in my pom.xml

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>

        </dependency>

>Solution :

if you look inside of GroupedOpenApi you will see that builder() is a static method:

public static Builder builder() {
    return new Builder();
}

as well as the constructor is private:

private GroupedOpenApi(Builder builder) {
   ...
}

Therefore simply remove the keyword new for it to work:

@Bean
public GroupedOpenApi api() {
    return GroupedOpenApi.builder()
                .pathsToMatch("/path/**")
                .build();
}
