In Chapter4, I explained how you could pass some JSON content on the command line to the Cordova Create command to automatically set configuration values in the project's config.json file (.cordova/config.json):

cordova create test2 com.johnwargo.test2 Test2 "{\"plugin_search_path\":\"d:/dev\"}"

This no longer seems to be working with later versions of the CLI. I've asked the Cordova Development team to clarify.
