Require ember-auto-import >= 2 or higher with ember-source@4.0.0

[rwjblue]

In order to allow ember-source to migrate to be a V2 addon, we must require that ember-auto-import@2 is present in the consuming application.

Concretely, we should add code to the addon entry point to check this.project.addons includes ember-auto-import@2 installed. That code would go somewhere around here:

ember.js/lib/index.js

Line 45 in e53d6bb

init() {

@rwjblue, I’ve noticed that, as a side-effect of this, addons will have to include ember-auto-import >= 2 as a dependency to run tests against ember >= 4 (even if they don’t use it). I haven’t seen a discussion around this in the run-up to v4, and I have a sneaking feeling this might come as a surprise to a lot of addon maintainers. Might it be worth releasing some guidance on this with the release?

As an alternative to forcing all apps downstream to use auto-import v2, I’m probably going to be taking advantage of ember-try scenarios for the next while. Or as long as the test suite has a version of ember <4. sandydoo/ember-google-maps@3c78cba

Found this comment #19761 (comment). Luckily, the devDependencies option works in my case!
