Fehler beim Scannen des Eintrags "module-info.class" beim Starten von Jetty-Server

Question

Ich sehe dies erst kürzlich, als ich meinen Java-Server starte. Hat jemand anderes das gesehen? Wenn ja, was ist das Problem? Ich kann bestätigen, dass die Jars und die Modul-info.class in den relevanten Pfaden vorhanden sind.

Answer 1

module-info.class ist eine JDK9 (JPMS) -Funktion.

Jetty nicht unterstützt JDK9 (noch)

Ausgabe darüber bei https://github.com/eclipse/jetty.project/issues/1692

Unterstützung für module-info.class in JAR-Datei Scannen ignoriert wird in einer zukünftigen Jetty 9.4.x Release erscheinen.
