Org.apache.nutch.crawl.Crawl missing in nutch 1.9 on hadoop 1.2.1

I have installed fully distributed Hadoop 1.2.1. I tried to integrate nutch with the steps below:

• Download apache-nutch-1.9-src.zip
• Add value http.agent.name to nutch-site.xml
• Copy hadoop-env.sh
  
  , core-site.xml
  
  , hdfs-site.xml
  
  , mapred-site.xml
  
  , masters
  
  , slaves
  
  to $ NUTCH_HOME / conf
• compile with ant runtime
  
  
• create urls/seed.txt
  
  and put on hasoop dfs
• modify $ NUTCH_HOME / conf / regex-urlfilter.txt

Test bypass using the command:

bin/hadoop -jar nutch-1.9.job org.apache.nutch.crawl.Crawl urls -dir urls -depth 1 -topN 5

and get this error:

Exception on thread "main" java.lang.ClassNotFoundException: org.apache.nutch.crawl.Crawl   at java.net.URLClassLoader $ 1.run (URLClassLoader.java:366) at java.net.URLClassLoader $ 1.run (URLClassLoader.java : 355) at java.security.AccessController.doPrivileged (native method) at java.net.URLClassLoader.findClass (URLClassLoader.java:354) at java.lang.ClassLoader.loadClass (ClassLoader.java:425) at java.lang.

I tried extract nutch-1.9.job and I didn't recognize the Crawl class in org / apache / nutch / crawl.

Do I need to configure something?
