Could not find or load main class org.apache.solr.

问题:

I kept getting the error "Could not find or load main class org.apache.solr.util.SolrCLI" while trying to setup SOLR on windows x64 machine.

The resolution to the problem is really simple. 1)start solr. notice that you have to use solr.cmd instead of just solr

*bin/solr.cmd start*

2) then create the collection:

*bin/solr.cmd create -c gettingstarted -p 8983*

3) then add file/s to index using post tool. You can execute the post command in two ways

a)java -Dc=gettingstarted -jar post.jar *.json

or

b) bin/post -c gettingstarted example/exampledocs/books.json

Now you can navigate to your newly created collection 'gettingstarted' and query your books.

`http://localhost:8983/solr/#/gettingstarted/query'

Hope this saves someone's time.
