Remove /t characters from swagger.yaml

[pulse0ne]

/t (tab) characters cause problems in some versions of swagger-codegen-cli

great, Tyler!
What language/implementation/version of codegen causes what err?

What is your business connection with NASA's UTM? afaik I have not met you.

Hey Irene,
I was generating Java (spring, specifically) with swagger-codegen-cli v2.3.1. My config looks like this:

{
  "library": "spring-boot",
  "java8": "true",
  "dateLibrary": "java8",
  "modelPackage": "gov.nasa.utm.utmcommons.model",
  "useBeanValidation": "true"
}

The company I work for is exploring FIMS/UTM development. Thank you for your time!

Edited to add the error:

java -Dmodels -DmodelDocs=false -DapiDocs=false -jar swagger-codegen-cli.jar generate -v -l spring -c ./scripts/config.json -i ./utm-apis/fimsauthz-api/swagger.yaml -o ./utm-models

The error doesn't tell you much, but I tested with a more recent version of the 2.x swagger-codegen-cli (v2.4.9) and it specifically called out the \t(TAB) characters as the cause of the parse error:
