How to generate metadata info with openapi-generator

Question

In my openapi.yaml file there are some information I would like to access in my code.

openapi: "3.0.0"
info:
  title: Title
  description: My description
  version: "1.0"

Now I would like to be able to access the version information contained in the api-specification. Is there a way to tell the generator to generate these metadata?

I am using the openapi-generator-maven-plugin with the spring generator.

Hopefully this will helpful. I'm using this plugin to get the MetaData information, this will generate configuration class

<plugin>
                <groupId>org.openapitools</groupId>
                <artifactId>openapi-generator-maven-plugin</artifactId>
                <version>7.6.0</version>
                <executions>
                    <execution>
                        <id>openapi-generator</id>
                        <phase>generate-sources</phase>
                        <goals>
                            <goal>generate</goal>
                        </goals><!---->
                        <configuration>
                            <inputSpec>
                                ${project.basedir}/src/main/resources/petstore.yml
                            </inputSpec>
                            <library>spring-boot</library>
                            <generatorName>spring</generatorName>
                            <apiPackage>com.example.openapigenerator.api</apiPackage>
                            <modelPackage>com.example.openapigenerator.model</modelPackage>
                            <configOptions>
                                <GenerateOpenAPIMetadata>true</GenerateOpenAPIMetadata>
                            </configOptions>

                        </configuration>
                    </execution>
                </executions>
            </plugin>

Basically this config helping to get this information

<configOptions>                            
      <GenerateOpenAPIMetadata>true</GenerateOpenAPIMetadata>
</configOptions>
