GWT and libgdx with Java SDK (no gwt.xml files)

Hi, does anyone know how we can use the Java SDK GitHub - auth0/auth0-java: Java client library for the Auth0 platform in Google Web Toolkit?

Basically I have a libgdx app at TuxFight and Auth0 is working perfectly on desktop and Android. However, I can’t use the Java SDK with GWT because it says the gwt.xml files are not available. I tried to copy the sources to the source packages of my project in Android Studio (under the html subproject) and create my own gwt.xml file, but it didn’t work.

Is there any way to use the Java SDK with GWT (generate for HTML)? I know I can just generate the endpoints on my own but it is so much nicer to be able to use things like authorize() and userInfo() rather than reinvent the wheel.
