OpenAPI models not being generated when using oneOf - swagger

Question

I am using OpenAPI+OpenAPI-generator with spring boot, and trying to use the schema oneof as follows:
This is the configuration in the requests.yaml file:
...
requestBody:
name: request
required: true
content:
application/json:
schema:
oneOf:
- $ref: 'components.yaml#/Request'
- $ref: 'components.yaml#/ComplexRequest'
...
and this is the relevant configuration in the components.yaml file:
Request:
allOf:
- $ref: '#/BaseInfo'
- type: object
properties:
should_create:
type: boolean
enum: [ false ]
reference_id:
type: string
required:
- reference_id
ComplexRequest:
allOf:
- $ref: '#/BaseInfo'
- type: object
properties:
should_create:
type: boolean
enum: [ true ]
create_data:
$ref: '#/Reference'
required:
- create_data
BaseInfo:
type: object
properties:
customer_id:
type: string
Reference:
type: object
properties:
propery_1:
type: string
propery_2:
type: string
propery_3:
type: string
For some reason, all of these components and only these are not being generated.
Can someone enlighten me on what am I doing wrong here?

Answer 1

If someone is facing this issue, I hope I'll save you some investigation time;
As for March 2022, it seems like oneOf (and anyOf) is just not supported by openapi-generator:

And though not compatible for my situation, you can try the solutions suggested here:
