Nutch 1.11 crawl Issue

I have followed the tutorial and configured nutch to run on Windows 7 using Cygwin and i'm using Solr 5.4.0 to index the data

But nutch 1.11 is having problem in executing a crawl.

Crawl Command $ bin/crawl -i -D solr.server.url=http://127.0.0.1:8983/solr /urls /TestCrawl 2

Error/Exception

hadoop-core jar file is needed when you are working with nutch

I can see there are multiple problems with your command, try this:

bin/crawl -i -Dsolr.server.url=http://127.0.0.1:8983/solr/core_name path_to_seed crawl 2

The first problem is that there is a space when you pass the solr parameter. The second problem is that the solr url should include the core name as well.
