It seems like you're using a project generated using an old version of the Angular CLI.
The latest CLI now uses webpack and has a lot of improvements including a simpler
workflow, a faster build, and smaller bundles.
To get more info, including a step-by-step guide to upgrade the CLI, follow this link:

It seems like you're using the newest version of the Angular CLI that uses webpack.
This version does not require an angular-cli-build file, but your project has one.
It will be ignored.
