Looks like the required plugin aint present in the configuration file [0].Can you try adding "protocol-httpclient" to plugin.includes property in conf/nutch-site.xml ? Like this
<property> <name>plugin.includes</name> <value>protocol-(http|httpclient)|urlfilter-regex|parse-(html|tika)|index-(basic|anchor)|indexer-solr|scoring-opic|urlnormalizer-(pass|regex|basic)</value> <description>Regular expression naming plugin directory names to include. Any plugin not matching this expression is excluded. In any case you need at least include the nutch-extensionpoints plugin. By default Nutch includes crawling just HTML and plain text via HTTP, and basic indexing and search plugins. In order to use HTTPS please enable protocol-httpclient, but be aware of possible intermittent problems with the underlying commons-httpclient library. </description> </property> Let us know if that worked.
