Fix sourceType docs to include YAML/YAMLSCHEMA in Maven, Gradle and Ant

[flemming-n-larsen]

I have tried out using YAML schema (issue #778) with the newest version of jsonschema2pojo, and it seems to work perfect. Thanks! :-)
However, the tools for generating Java code is not supporting YAML Schema in version 0.5.0 and 0.5.1. It would be cool, if the Maven, Gradle, and Ant tool support YAML schema as well.
Personally, I use the Maven plugin to generate POJOs from .json files, but should love you use .yaml / .yml files instead.

Hi.

Sorry, could you explain how this is not supported? Are you having trouble using sourceType yaml or yamlschema?

[joelittlejohn]

Closing this as I think there's nothing to do. Feel free to re-open if you think I've missed something.

Thanks. The sourceType works as a charm. I have now converted all my JSON types into YAML types and use the Maven plugin to generate the POJOs for GSON. 👍

However, I am missing your description of the sourceType yamlschema and yaml in the description for the Maven plugin here:
https://joelittlejohn.github.io/jsonschema2pojo/site/0.5.1/generate-mojo.html

The same thing goes for the the sourceType description for the Gradle plugin:

Yeah, I must have missed updating the docs here. Thanks!
