Description

The mustache template does too much and it would help to remove the :{{complexType}} insert and leave the the spaces out of the curly brace after the square bracket so that you have:

#' @field {{baseName}} {{title}} {{^isPrimitiveType}} \link[{{packageName}}]{{{/isPrimitiveType}} {{#isContainer}} {{#isListContainer}}list({{#items}}{{dataType}}{{/items}}){{/isListContainer}}{{#isMapContainer}}named list({{#items}}{{dataType}}{{/items}}){{/isMapContainer}} {{/isContainer}}{{^isContainer}}{{dataType}}{{/isContainer}} {{^isPrimitiveType}}} {{/isPrimitiveType}} {{^required}}[optional]{{/required}}

I have not tested this as I was unable to run it locally. I kept getting errors when using the
openapi-generator-cli-4.2.0.jar file.
