Open API -> How to reference the external property names/types of Java objects of class path/jar in Request or Response Body YAML Specification - yaml

Question

my requirement is to use the properties names and types of the classes which are included in class path java objects.
Basically, $ref will allow us to use the classes which are included in class path like below
1) **YML File**
paths:
/users/{id}:
parameters:
- name: id
in: path
required: true
description: the user identifier, as userId
schema:
type: string
get:
responses:
'200':
description: the user being returned
content:
application/json:
schema:
$ref: "**TESTCALSSOFCLASSPATHORJAR**"
properties:
uuid: # the unique user id
type: string
format: uuid
2) <plugin>
<groupId>org.openapitools</groupId>
<artifactId>openapi-generator-maven-plugin</artifactId>
<version>${openapi-generator-maven-plugin.version}</version>
<configuration>
... excluded for simplicity
<importMappings>
<importMapping>TESTCALSSOFCLASSPATHORJAR=path.to.your.TESTCALSSOFCLASSPATHORJAR</importMapping>
</importMappings>
</configuration>
</plugin>
Is there any way that, I can refer id attribute name from my class path/jar java object??
paths:
/users/{id}:
parameters:
- name: **id** -> I want to get this prop from TESTCALSSOFCLASSPATHORJAR class
i.e.TESTCALSSOFCLASSPATHORJAR.id
in: path
required: true
description: the user identifier, as userId
schema:
type: string
get:
responses:
'200':
description: the user being returned
content:
application/json:
schema:
$ref: "**TESTCALSSOFCLASSPATHORJAR**"
properties:
uuid: # the unique user id
type: string
format: uuid
Referred below documents and searching a lot but didn't find any solution.
