I get above result while running nutch1.13 with solr6.6.0
command i used is
bin/crawl -i -D solr.server.url=http://myip/solr/nutch/ urls/ crawl 2
below is plugin section in my nutch-site.xml
<name>plugin.includes</name>
<value>
protocol-(http|httpclient)|urlfilter-regex|parse-(html)|index-(basic|anchor)|indexer-solr|query-(basic|site|url)|response-(json|xml)|summary-basic|scoring-opic|urlnormalizer-(pass|regex|basic)
</value>
Below are my file contents
