I'm using openAPI spec to generate the data models. However for one specific model (eg: error model), this is defined in a common separate library(jar) and want to use the same instead of the one generated from openAPI spec.
is there an option in $ref to say that this is an external model?
$ref: '#/definitions/Error' # means go to the root of the current document and then find elements definitions and Error one after one
but i want to use the Error Model defined in a sperate common library and how to indicate the same in openApi spec.
