4 years ago Further on the problem, It seems related to the Ignore Case. When Provide HTTP it fail but if change it to http surprisingly it compiles just fine. When I look at the code for the type it is ignoreCase still it fails.
bearer: type: "HTTP" scheme: "bearer"
I upgraded from Swagger 2.0 to OpenApi 3.x and ran into issues around Security Schemes. I defined securitySchemes bearer but it is failing with NPE when generating code around generators.DefaultCodegenConfig.fromSecurity . I recreated the issue with a very simple YAML file. It generates code fine from swagger UI hence something to do with code-gen used from CLI.
Steps to reproduce: swagger-codegen generate -i provided_swagger.yaml -l jaxrs-jersey
Error:

Simplified Security Scheme usage :
securitySchemes: bearer: type: http scheme: bearer
