Support for watch mode

[ghost]

The plugin is working fine. The only problem I see is when I use with clean-webpack-plugin using watch mode of webpack. The first reload of webpack, it goes fine, the webpack cleans the dist folder and the plugin generates the json perfectly. The second time it reloads, the clean-webpack-plugin cleans the folder and the json is deleted. There is a way to keep regenerating json file every time webpack recompiles? Thank you!
