在线程"main"java.lang.NoClassDefFoundError:com/google/common/util/concurrent/FutureCallback中获取错误异常,同时在代码下运行.请告知我缺少哪个Jar文件.我正在从Eclipse IDE执行

      Metadata metadata = cluster.getMetadata();

      System.out.printf("Connected to cluster: %s\n", metadata.getClusterName());

      for ( Host host : metadata.getAllHosts() ) {

      }
   }

   public void close() {
      cluster.shutdown();
   }

   public static void main(String[] args) {
      DataStaxPOC client = new DataStaxPOC();
