Migration Issue

In the project GroovyFX (see source code), upgrading to OpenJDK 17 and Gradle 7.6 I got this error:

Could not find class for Transformation Processor groovyx.javafx.beans.FXBindableASTTransformation declared by groovyx.javafx.beans.FXBindable

The FXBindableASTTransformation is used as annotation in FXBindable. This used to work under Java 8.
How can I prevent this error?

This is a fork of the groovyfx project: https://github.com/wise-coders/groovyfx.

You can test it by executing

cd groovyfx
gradlew build
gradlew runAccordionDemo
