standalone pushfilter：jetty.server.request not found

如果與jetty一起使用，我正在開發一個獨立過濾器來擴展我們的webapp（BaseX）。目標是在響應發送時推送一些附加資源。 Web應用程序定義了必須推送哪些資源。standalone pushfilter：jetty.server.request not found

隨着嵌入式碼頭，一切順利。但是部署BaxeX ALS Servlet時到碼頭，開始jettx：運行分叉，我得到這個：

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)

...

這是過濾器的pom.xml：

和我加載它依賴這裏：

     <artifactId>xmldb-api</artifactId> 
    </dependency> 
    ...

爲什麼我不能從W中訪問服務器類很明顯ebapp！ webapp不應該對周圍的servlet容器有任何依賴關係，因爲它可能會改變。

這就是爲什麼我實現了過濾器獨立，但不知何故它仍然無法訪問server.Request類。 Jetty的PushCacheFilter也使用jetty.request類，它應該是可能的！

我怎樣才能解決這個問題？我堅持:(

THX很多
