swagger-maven-plugin: OPERATION annotation with multiple TAGS does not correctly generate openapi.json using inheritance in Java

[anadal-fundaciobit]

I have two classes that implement the same operation defined with Swagger annotations in a Java interface. I define two tags using the @operation annotation. The problem is that the operation is duplicated in each Service where I use them.

INTERFACE:

SERVICE 1:

SERVICE 2:

Swagger-maven-plugin definition (pom.xml):

SWAGGER UI SERVICE 1:

SWAGGER UI SERVICE 2:

I am using io.swagger.core.v3::swagger-maven-plugin::2.2.20 and java 11

openapi_signature_v1.json
