problem is that i did not have the plugins configured!!
so make sure you have a plugin directory on your filesystem
with all the plugins listed at <name>plugin.includes</name>
and nutch-extensionpoints as well and make sure
nutch-default.xml or nutch-site.xml will point to that directory at
<name>plugin.folders</name>
