Trying to generate OpenAPI documentation using the springdoc-openapi-maven-plugin.
https://springdoc.org/#plugins
I added the springdoc-openapi-maven-plugin configuration exactly as suggested in the documentation. I already had the spring-boot-maven-plugin configures, and I also added the goals start/stop as suggested in the https://springdoc.org/#plugins
Running mvn verify fails
[INFO] --- springdoc-openapi:1.4:generate (integration-test) @ my-application ---
