Hi!

when I use a different path than "../resources/openapi" for my API definition and omit the directory completely, then compilation fails. When I just add an empty directory "openapi" but keep using the different path it works without any problems.

How to reproduce:

1. Delete the directory "openapi" or don't even create it
2. Define a different path in application.properties: quarkus.openapi.generator.spec=../test/openapi.yaml
3. (mvn clean)
4. mvn compile

Result:

Compilation fails due to missing referenced imports. No error message suggesting the missing file or directory.

Possible workaround:

Just add an empty directory "openapi" in resources. If Git can't handle the empty directory just put in a dummy file.

Versions used:

quarkus-openapi-generator: 2.6.0
Quarkus: 3.15.2
Java: 21
maven-compiler-plugin: 3.9.6
