mbknor-jackson-jsonSchema | Generate JSON Schema with Polymorphism | JSON Processing library

I am writing a gradle plugin to generate a json-schema for beans in my project. My goal is to have the schema generated and published as part of the build process so I don't need to keep updating it manually.

Currently, I pass project.compileJava.inputs.files to my task and use that to construct a URLClassLoader. Then I pass those classes to a schema generator.

In order to ensure that the json schema is generated correctly, I want to use the ObjectMapper from the target application. Unfortunately, my ObjectMapper adds the jackson Hibernate5Module. In the depths of that module, it tries to check if my class is assignable to a HibernateProxy, and since the HibernateProxy is loaded with Gradle's class loader and my class is loaded with the URLClassLoader everything explodes.

I could remove the Hibernate module, but that still leaves the bug to be triggered in other similar situations, and it makes my plugin less distributable. So I need a way to either add new entries to gradle's classpath or to the default class loader at run time.

For reference, here are the relevent code snippets:
