Wie verwende ich Spring Boot, wenn Jetty 9.3 auf dem Klassenpfad ist?

Question

Ich habe ein Spring Boot-Projekt, und ich versuche, von Solr 5.4 auf Solr 6.1 zu aktualisieren. Solr 6.1 ist von Jetty 9.3 abhängig. Jetzt beschwert sich Spring Boot: es gibt eine NoClassDefFoundError: org/eclipse/jetty/server/handler/ContextHandler$NoContext. ContextHandler existiert in Jetty 9.3, aber nicht in der inneren Klasse NoContext.

Gibt es eine Möglichkeit, dies zu lösen?

mit Frühlings-Boot 1.3.6 arbeitete folgende Anlegestelle gradle Config fein:

dependencies { 
compile("org.springframework.boot:spring-boot-starter-web") { 
    exclude module: "spring-boot-starter-tomcat" 
} 
compile("org.eclipse.jetty:jetty-webapp:9.3.10.v20160621") 
compile("org.eclipse.jetty:jetty-jsp:9.2.17.v20160517")
