Description

I’m trying to use openapi-generator with a simple yaml and use it to auto-generate some code for my project. However, when I try to build my project I get this error:

[ERROR] src/service/target/generated-sources/src/main/java/org/openapitools/configuration/OpenAPIDocumentationConfig.java:[14,48] cannot find symbol [ERROR] symbol: class RelativePathProvider [ERROR] location: package springfox.documentation.spring.web.paths

In addition in OpenAPIDocumentationConfig.java, I see that: @javax.annotation.Generated(value = “org.openapitools.codegen.languages.SpringCodegen”, date = “…”) and @EnableSwagger2

while I was expecting not to include @EnableSwagger2 and have this type of generator: @javax.annotation.Generated(value = “io.swagger.codegen.v3.generators.java.SpringCodegen”, date = “…”)

Following you can also find relevant part of my pom.xml:

I cannot understand how the generator builds a code that do not compile and why it uses old swagger 2 instead of OAS 3.
