trying to use the Bash code generator, but bash isn't in the list of supported languages?

Description

This may be a dumb question, or maybe I'm just doing it wrong, but I'm unable to get the Swagger code generator to work out-of-the-box to generate Bash client code.
I am able to get it working to generate Ruby and Java client code, but not bash.

Is there something special I need to do to get bash code generation working and I just missed it in the README?

Swagger-codegen version

I'm using: https://repo1.maven.org/maven2/io/swagger/codegen/v3/swagger-codegen-cli/3.0.30/swagger-codegen-cli-3.0.30.jar

Swagger declaration file content or url

I can provide the swagger JSON if necessary but that doesn't seem to be the issue here because the JSON works fine for other languages.

Command line used for generation

> java -jar swagger-codegen-cli-3.jar generate -l bash -i ~/Downloads/myapi.json -o ./myapi-client

Suggest a fix/enhancement

Start by reproducing the command shown in the issue and read CodegenConfigLoader.java and SwaggerCodegen.main from the stack trace to understand how available languages are registered. Check how existing Ruby or Java generators are exposed, then verify that Bash appears in the supported-language list and that the documented generation command completes successfully.
