We are using Quarkus 3.12.3 with io.quarkus:quarkus-smallrye-openapi to generate OpenAPI document at both build time and runtime, we also use the swagger-ui properties to include the Swagger UI with our application.

We need to augment/combine some static OpenAPI content in a file with the above generated OpenAPI document. The docs say to place the static content in META-INF/openapi.yaml or to specify the custom location via additional-docs-directory, However neither of those approaches work, the static content is never combined with the generated OpenAPI results.

How can I enable the combining of content?

We placed the static content at the location specified in the documentation. We were expecting it to work per the documentation.
