[BUG][JAXRS-spec] useOneOfInterfaces option causes compilation error #17419

Open jerui1 opened 9 months ago

jerui1 commented 9 months ago
Description

When using the useOneOfInterfaces option, the generated code does not compile.

Children classes are OK, but the generated parent is a class instead of an interface.

openapi-generator version

I've reproduces the issue with openapi-generator-maven-plugin : 7.0.1, 7.1.0 6.6.0

The option does not seem supported on previous releases.

Reproduced on openapi-generator v7.2.0

The issue still occurs with openapi-generator v7.3.0

The same issue also occurs with jaxrs-resteasy generator (--additional-properties=useOneOfInterfaces=true). The expected interface for the oneOf schema is not generated and a class with the same name is generated in its place. However, the classes generated for the subschemas correctly implement the intended interface.

This has been open for 6 months without any resolution, is anyone maintaining this?
