"ember build" Fails in Nested Addon Situation

I have a custom addon (i.e. @adc/i18n) which lists ember-intl@^3.0.0 as a dependency. Running the dummy application for @adc/i18n works without issue. However, when I try to include @adc/i18n within another custom addon of mine as a dependency (i.e. @adc/list-row), I receive the following build error:

ERROR Summary:

It seems like the line it’s failing on is if (!this.opts.publicOnly) in the treeForApp hook. I can see that this.opts is hit in the included hook, so I’m not sure what is happening. I have an config/ember-intl.js file defined in both @adc/i18n and in @adc/list-row. Oddly, when I change ember-intl to be a devDependency inside @adc/i18n, this allows for a successful build. However, I want it as a dependency.

Any thoughts on why the options are undefined or how to fix it?

Oh my goodness. I had…

included() {
    this._super.apply(this, arguments);
}

…and was missing the included method. Thanks so much for pointing me in the right direction. Sorry for the inconvenience.

Ah, I believe I know what is happening here. Thanks for the thorough explanation, I’ll try and have a fix today or tomorrow.
