Description

From the openapi definition (see below) when I open it in the online editor https://editor.swagger.io/ I get the following swagger-ui page. Only the tags present in the definition appear.

When I use the JavaSpring generator with the same openapi definition, the generated java interface contains @Tag annotation on the generated interface deduced from endpoint path, with automatic generated description value.

And the swagger-ui page display it in addition to the one already present in the definition.

I don't want the generated tag because I define mine directly in the definition.
I don't found an option (in the documentation nor in the api.mustashe) to avoid this generation.

Generation Details

The genererated interface contains :

@Generated(value = "org.openapitools.codegen.languages.SpringCodegen")
@Validated
@Tag(name = "auth", description = "the auth API")
public interface AuthApi {
[...]
    /**
     * GET /auth/login : API for login
     *
     */
    @Operation(
        operationId = "authLogin",
        summary = "API for login",
        tags = { "authentication" },
        [...]

Suggest a fix

Start with the JavaSpring generator and its api.mustache template, then compare the generated interface's inferred @Tag with the OpenAPI definition's declared tags. Reproduce the example using the supplied YAML and confirm that generation no longer adds an unwanted tag when the definition already provides one.
