I've just installed the plugin to an existing ember-cli 1.13.13 app, and when I generate a pod or a component I am getting javascript blueprints for the pod itself, but coffeescript for the tests.
I tried adding
ENV.coffeeOptions = {
blueprints: true
}
to try to force it but it is still not happening. Is there anything else I was supposed to do besides ember install ember-cli-emberscript ?
