UnhandledPromiseRejectionWarning, when no files match /**/*.s?(c|a)ss

[leosuncin]

The plugin fail when not found stylesheets for lint and break webpack build, this is a problem in some cases when you're starting a project without styles or embed styles in HTML

Error: /home/leosuncin/Workspaces/github/writtr-frontend/**/*.s?(c|a)ss does not match any files

You can clone my repository and view the error

This might be an upstream issue with stylelint itself, because I don't think there should be an unhandled rejection when a files are not found in the lint function. All this plugin does is call stylelint.lint and use the results, and if there's an error it should be contained in the error object that we print to the console.

That being said if you can reproduce it with a failing test in this repo, that would be awesome :)

@JaKXz, it's actually quite easy to reproduce.

Same problem here. The plugin fails with an error if the context folder contains no stylesheets at all.

Admittedly, this may not be relevant for production builds, but it is quite annoying in other scenarios. For example, I've been running running tests cases on some of my application components with the same webpack configuration as for the actual application. After integrating stylelint-webpack-plugin, these test cases are now failing for all components that don't have stylesheets in their folders/subfolders.

any news on this? having no stylesheet breaks compilation

It's pretty important in scenarios with reusable webpack configurations. Several projects may share the same config but not all may have .css files.
