Trying to insert data into the auto generated code from a configuration file

So I am editing a mustache file to get the auto generated code to wait for some time before doing an action.

The mustache file looks like:
`double wait_time_double = {{wait_time}};'
'int wait_time = (int) (wait_time_double * 1000);'
'Thread.sleep(wait_time)'

I want to allow a user to set wait_time from a cli that I am making separate from swagger. So users never have to deal with the swagger interface for auto generating code. I am able to take the users input and add it to the swagger.json api file so it looks like this:

{"swagger": "2.0",
"info": {
"description": "A sample applications",
"version": "0.0.1",
"title": "Hello WebApp",
"contact":
"name": "Sample application"
}

... more api code

"wait_time":"0.1"
}

Then i call the code generator by calling:
swagger-codegen generate -i swagger.json -t timplate.mustache -l java -o output.java

However; this does not get swagger to give the mustache file the wait_time variable.

Any help would be greatly appeciated

Swagger-codegen version

2.2.2

Start with the custom template and the swagger.json passed to swagger-codegen generate, then check how version 2.2.2 exposes definition fields to Mustache templates. Confirm whether the top-level wait_time value is available during Java generation; done means the generated output contains the configured value.
