[pradeepkumarreddyk]

Description

I have used the following dependency in android studio to download the swagger-codegen-cli jar file:-
compile "io.swagger:swagger-codegen-cli:2.1.4"

Then, I'm using the following command

Command line used for generation

java -jar swagger-codegen-cli-2.1.4.jar generate -i generate_upload.yml -l android --library=volley -o generated_code_for_upload_resource/ -c generate_config.json

and i'm getting the following exception:-

Exception in thread "main" java.lang.RuntimeException: unknown library: volley
at io.swagger.codegen.DefaultCodegen.setLibrary(DefaultCodegen.java:1637)
at io.swagger.codegen.config.CodegenConfigurator.toClientOptInput(CodegenConfigurator.java:307)

at io.swagger.codegen.SwaggerCodegen.main(SwaggerCodegen.java:35)

Swagger-codegen version

i'm using 2.1.4 version of swagger codegen

Steps to reproduce

1. include the following dependency in android studio
   compile "io.swagger:swagger-codegen-cli:2.1.4"

this downloads the jar file.

2. using this jar file, try to generate the code using the following command line

java -jar swagger-codegen-cli-2.1.4.jar generate -i generate_upload.yml -l android --library=volley -o generated_code_for_upload_resource/ -c generate_config.json

3. I'm getting exception as unknown volley library

The Android volley support was added in 2.1.5: #1775

I would suggest you to upgrade to the latest stable version: 2.2.1.

I want to generate java code from my yaml file, but got same error: "unknown library: xxx"

• I created the java-proj.json :

{
    "library": "proj",
    "artifactId": "swagger-proj"
}

• and proj-test.sh :

...
ags="$@ generate -i swagger-file.yaml -l java -c java-proj.json -o proj -DhideGenerationTimestamp=true"

1. For what is '-c' option? and java-proj.json file? what is 'proj' from "library": "proj"?

2. Without '-c' option I got java stubs but I want to generate also some test validations in each test.
   Now it generates comments like: '// TODO: test validations', how to achieve this?

[wing328]

proj is not a valid "library". For a list of supported library, please run java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar config-help -l java

@wing328 I tried this in json:
{ "artifactId": "swagger-proj", "library": "jersey2", "useBeanValidation": true }
No errors, but it does not generate the test data and validation like in jersey2 sample, how to achieve this? What else should I change/add ?
