A non declared argument, allowableValues, is placed for OAS 3.0 annotation @Parameter
The issue is related to an array of string set with a enum for a parameter named status, an example of this is /pet/findByStatus: path from petstore sample :
/pet/findByStatus:
get:
tags:
- pet
summary: Finds Pets by status
description: Multiple status values can be provided with comma separated strings
operationId: findPetsByStatus
produces:
- application/xml
- application/json
parameters:
- name: status
in: query
description: Status values that need to be considered for filter
required: true
type: array
items:
type: string
enum:
- available
- pending
- sold
default: available
collectionFormat: csv
responses:
'200':
description: successful operation
schema:
type: array
items:
$ref: '#/definitions/Pet'
'400':
description: Invalid status value
security:
- petstore_auth:
- 'write:pets' Command used:
java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate -i modules/swagger-codegen/src/test/resources/2_0/petstore.yaml -l jaxrs-cxf-cdi -o output -DhideGenerationTimestamp=true
Keeping in mind that it does not matter that definition is in OAS 2 format since Swagger Codegen v3 supports it.
So the generated output with error on PetApi.java class is:
public Response findPetsByStatus( @NotNull @Parameter(description = "Status values that need to be considered for filter",required=true, allowableValues="available, pending, sold") @QueryParam("status") List<String> status) {
return delegate.findPetsByStatus(status, securityContext);
}
when we try to build generated code with mvn package command we got:
[ERROR] /Users/hugomercado/GitHub/swagger-codegen/samples/server/petstore/jaxrs-cxf-cdi/src/gen/java/io/swagger/api/PetApi.java:[106,111] cannot find symbol [ERROR] symbol: method allowableValues() [ERROR] location: @interface io.swagger.v3.oas.annotations.Parameter
