I use eclipse to run NutchAnalysis.java, but it meet QueryFilter RunTime error

The erros are described here:
Exception in thread "main"
java.lang.RuntimeException:
org.apache.nutch.searcher.QueryFilter not found.

I debug QueryFilters.java:59 , 
try {
        ExtensionPoint point = PluginRepository.get(conf)
            .getExtensionPoint(QueryFilter.X_POINT_ID);
        if (point == null)//Realy null
          throw new RuntimeException(QueryFilter.X_POINT_ID
+ " not found.");

What should I do?
Thank YOU!
