我有一个Spring Boot项目，我正在尝试从Solr 5.4升级到Solr 6.1。 Solr 6.1依赖于Jetty 9.3。现在Spring Boot抱怨：它给出NoClassDefFoundError: org/eclipse/jetty/server/handler/ContextHandler$NoContext。 ContextHandler存在于Jetty 9.3中，但不存在于内部类NoContext中。
有没有办法解决这个问题？

答案 0 :(得分：1)
使用Spring Boot 1.3.6，以下jetty gradle配置工作正常：
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")
