Export ember project dependency licenses

I have a requirement for being able to export a list of dependency open source licenses of my Ember project's non-development dependencies.

We have some Node apps and I've been able to use license-checker, and that will output a a list for the Ember app as well.

The problem is that it doesn't seem to be possible to separate out the dev vs. non-dev dependencies (because ember-cli installs all dependencies in devDependencies). This means my export contains tons of build dependencies that we never actually ship.

I've looked at ember-cli-license which hasn't been updated in years and ember-cli-json-license which works but has the same problem.
