Path not present: components

[grnadav]

Hello,
When running the maven plugin on a json file (de-refed, all local definitions),
It can't find components in the json OpenAPI.
But it is there.
Using that JSON file we are able to generate a REST service using the generic OpenAPI generation tool.

Update:
Issue is with the ref of stuff_alias_identifier to base_identifier inside the components.
When embedded directly (removing base_identifier and writing its contents inside the other *_identifiers, it is able to generate the service.

we get this error:

Error from PROJECT_GENERATION_FAILED.txt :
