Before the switch to ESLint, we were able to fail the build for jsHint errors, using the method described here: [Force build failure on any JShint Error - #5 by hschmidt99](https://discuss.emberjs.com/t/force-build-failure-on-any-jshint-error/7060/5)

It wasn’t pretty but it worked. Is there a way to do this now with ESLint?

I wold like to add to the question: How to know what is causing the error?

I’m asking because in my particular case, all I get as a message running `ember server` is the following (no clue of what is wrong):

```

I wanted to answer my complement question: My project folder didn’t have the file `.eslintrc.js` in it (I found the hint at [1]).

This happened to me because I copied the project contents in a new folder cherry-picking the files, to avoid content like `dist`: but didn’t get the hidden files like `.eslintrc.js`.
