standalone pushfilter：jetty.server.request not found

如果与jetty一起使用，我正在开发一个独立过滤器来扩展我们的webapp（BaseX）。目标是在响应发送时推送一些附加资源。 Web应用程序定义了必须推送哪些资源。standalone pushfilter：jetty.server.request not found

随着嵌入式码头，一切顺利。但是部署BaxeX ALS Servlet时到码头，开始jettx：运行分叉，我得到这个：

java.lang.NoClassDefFoundError: org/eclipse/jetty/server/Request 
at org.basex.http2.BaseXJettyPushFilter.doFilter(BaseXJettyPushFilter.java:48) 
at org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1637) 
at org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:533) 
at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:143)

at org.eclipse.jetty.server.handler.ScopedHandler.nextHandle(ScopedHandler.java:190) 
at org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:1595)

...

和我加载它依赖这里：

    </dependency> 
    ...

为什么我不能从W中访问服务器类很明显ebapp！ webapp不应该对周围的servlet容器有任何依赖关系，因为它可能会改变。

这就是为什么我实现了过滤器独立，但不知何故它仍然无法访问server.Request类。 Jetty的PushCacheFilter也使用jetty.request类，它应该是可能的！

我怎样才能解决这个问题？我坚持:(

THX很多
