2. Navigate to http://mvnrepository.com/artifact/com.force.api/force-wsc in your browser and
download the WSC pre-built .jar file that matches the API version of Salesforce you’re using.

https://developer.mozilla.org/en-US/docs/Rhino/Download_Rhino and download the latest
.zip file. Un-archive the .zip file and move the folder to a location you’ll remember.
