Hello Nutch Developers,

How are plugins installed into Nutch?

The URLFilter plugin is already working from previous development but
my changes to the code don't take effect.

Here are the steps I've taken:
1. Modified the existing implementation of URLFilter interface 
2. Built the project with ant
3. Copied build/plugin/* to NUTCH_HOME/plugins
4. Ran the generate-fetch-index cycle

I modified filter() to write some debug statements to a file and
return null for every url (for debugging purposes). I know my code was
not executed because no urls should have been indexed and there were
debug statements in the file. I suspect that step 3 is what I am doing
incorrectly or there is some other file I need to modify.

I appreciate any help.

Thanks,
zennet
