Error with Apache nutch installation on windows 7
Hello All,
I have installed apache nutch 2.1 in windows7 and am using CYGWIN.
I have the following environment variables set:
JAVA_HOME : C:\Java\jdk1.7.0_07
NUTCH_HOME: C:\apache-nutch-2.1-src\ap
NUTCH_JAVA_HOME: C:\Java\jdk1.7.0_07
When I execute the command, "./bin/nutch crawl urls -depth 3 -topN 5" I get the error below:
Error: Could not find or load main class org.apache.nutch.crawl.Cra
Is there a permissions error here? Should I set my environment variables differently? Suggestions please?
Bewlow are some of the commands I have executed:
$ set | grep 'HOME'
ANT_HOME='C:\Program Files\ant'
HOME=/home/prasankr
HOMEDRIVE=C:
HOMEPATH='\Users\prasankr'
JAVA_HOME='C:\Java\jdk1.7.
NUTCH_HOME='C:\apache-nutc
NUTCH_JAVA_HOME='C:\Java\j
$ find ${NUTCH_HOME} -type f -name '*nutch*.jar'
C:\apache-nutch-2.1-src\ap
Executed:
./bin/nutch crawl urls -depth 3 -topN 5 2>&1 | tee nutch.log
Output:

I checked the classpath and still have issues but will look into reinstalling nutch.
There's no other interpretation of that exception. Many things can cause it, and it can be hard for new users to track down. Reinstalling nutch might fix it -- maybe there's an environment variable which wasn't set correctly.
