[RETROFIT2] Problem: com.github.jknack.handlebars.HandlebarsException

MichalDanielDobrzanski commented 5 years ago

Description

Cannot generate gradle module because of runtime exception with retrofit2. Using RxJava2 also.

Swagger-codegen version

3.0.1

Swagger declaration file content or url

I cannot post API, cause it is internal in the company.

Command line used for generation

swagger-codegen generate -i openapi.json -l java -c config.json -o /Users/mmdo/apis/test/

Steps to reproduce

Just run the script

Related issues/PRs

Suggest a fix/enhancement

Probably an injection into the script occured

Running into the same problem for 3.0.4

kmhughes commented 5 years ago

Does anyone know where these handlebar templates exist? I have built the code generator myself and just don't see where the templates are.

HugoMario commented 5 years ago

@kmhughes , templates are here https://github.com/swagger-api/swagger-codegen-generators/tree/master/src/main/resources/handlebars

kmhughes commented 5 years ago

Cool, thanks. I went looking and never found them, but apparently didn't look hard enough. Sigh.

Same issue here

simon-maling commented 5 years ago

I experienced the same issues, after some research I found that the issue has already been fixed in swagger generator v1.0.7. See https://github.com/swagger-api/swagger-codegen-generators/pull/318
