java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlElement when generating Hilla OpenAPI bindings using Gradle Plugin

[kjordan2001]

Describe the bug

I just upgraded to Vaadin 24.5 and am getting this error when I try to build my Gradle project that has a Hilla Endpoint in it:

Hi, could you, please, specify which version you're upgrading from? Also, would be great to know what adds Jaxb dependencies on the class path. AFAIK Hilla should not bring those.
