Generation Details

I need to generate a Spring Boot 2 and JDK17 compatible library. For that I use the following command:

java -jar openapi-generator-cli-7.9.0.jar generate -i openapi.yaml -g spring --additional-properties apiPackage=com.example.api.v1,artifactId=api-petstore,groupId=com.example.api,artifactVersion=1.0.0-SNAPSHOT,dateLibrary=java8,library=spring-boot,useJakartaEe=true,useSpringBoot3=false,useSpringController=false,skipDefaultInterface=true,modelPackage=com.example.model.v1,interfaceOnly=true,useSwaggerUI=false,useTags=true -o petstore_interface_only_sb2_jdk17 --global-property models,apis,supportingFiles=pom.xml

And then execute

mvn clean package

We choose useJakartaEe=true and useSpringBoot3=false. The output is a project that it does not compile, due to we are including jakarta packages but spring does not import the proper version of jakarta.validation and jakarta.annotation. Apart of this java.version should be 17.

Compile errors:

Suggest a fix

I suppose that I can fix the template including some if/else conditions but I don't know if I have to consider other things.

I wonder if you can file a PR to start with and we will review accordingly.
