Relative reference in external jar is resolved as a URL instead of RELATIVE

I have a service project in which OpenAPI schemas are included via a jar file. Inside this jar file, the schema contains a relative reference to another fragment in the same jar.

These are the references:

api.json (service project)
 -> Persons.json (jar)
   -> Person.json (relative ref in same jar) 

The reference is resolvable from the service to Persons.json in the jar. However, the relative reference within the jar from Persons to Person is resolved as URL instead of RELATIVE. This generates this error:

java.net.MalformedURLException: no protocol: /Person.json

Investigation into ExternalRefProcessor shows that this code strips the leading dot off the reference from Persons to Person:

https://github.com/swagger-api/swagger-parser/blob/v.1.0.33/modules/swagger-parser/src/main/java/io/swagger/parser/processors/ExternalRefProcessor.java#L163

Which causes it to be treated as a URL:

https://github.com/swagger-api/swagger-parser/blob/v.1.0.33/modules/swagger-parser/src/main/java/io/swagger/parser/processors/ExternalRefProcessor.java#L131-L134

Hi @gracekarina, I checked it out and the fix in PR https://github.com/swagger-api/swagger-parser/pull/658 has resolved my issue. I have updated openapi-service and it builds correctly using the 1.0.35-snapshot version. Thanks for the quick fix!

I’ll close it no problem. It was fixed by #658
