NoClassDefFoundError: Die Klasse groovy.xml.jaxb.JaxbGroovyMethods kann nicht geladen werden, weil die Abhängigkeit javax/xml/bind/Unmarshaller fehlt

Unser Gradle-Build muss --add-modules=Java.xml.bind,Java.activation,Java.xml.ws.annotation bis options.compilerArgs in JavaCompile mit JDK9/10 erstellt werden. Das funktioniert im Moment gut, aber diese Module sind veraltet.

Ich möchte mich auf JDK11 vorbereiten, wo diese Module entfernt werden könnten .

Ich habe versucht, javax.xml.bind:jaxb-api:2.3.0, com.Sun.xml.bind:jaxb-impl:2.3.0 und com.Sun.xml.bind:jaxb-core:2.3.0 zu compile und runtime sowie classpath in buildscript hinzuzufügen, aber ich erhalte trotzdem NoClassDefFoundError. 

Was vermisse ich?

Die gemeldete fehlende Klasse ist bei jedem Build nicht zu 100% identisch: Sie wechselt zwischen Beschwerden über javax/xml/bind/JAXBContext, javax/xml/bind/Unmarshaller und javax/xml/bind/Marshaller.
