n-webpack/lib/addons/verify-build.js

	try {
	compareArrays(builtFiles, expectedFiles)
	} catch(e) {
	throw `${e} is in your .gitignore but has not been built - is the build broken, or do you need to remove a line from .gitignore?`;
	}
	try {
	compareArrays(expectedFiles, builtFiles)
	} catch(e) {
	throw `${e} has been built but is not in your .gitignore - is the build broken, or do you need to add a new line to .gitignore?`;
	}
