Problem compiling FeedParser plugin with Nutch 2.1 source

[Anand Bhagwat]

Hi,
I want to use FeedParser plugin which comes as part of Nutch 2.1
distribution. When I am trying to build it  its giving compilation errors.
I think its using some classes from Nutch 1.6 which are not available. Any
suggestions as to how I can resolve this issue?

  *[javac]
/home/adminibm/Documents/workspace-sts-3.1.0.RELEASE/nutch2/src/plugin/feed/src/java/org/apache/nutch/indexer/feed/FeedIndexingFilter.java:28:
cannot find symbol
    [javac] symbol  : class CrawlDatum
    [javac] location: package org.apache.nutch.crawl
    [javac] import org.apache.nutch.crawl.CrawlDatum;
    [javac]                              ^
    [javac]
/home/adminibm/Documents/workspace-sts-3.1.0.RELEASE/nutch2/src/plugin/feed/src/java/org/apache/nutch/indexer/feed/FeedIndexingFilter.java:29:
