I’ve not enjoyed my experiences with TravisCI; false positives and inconsistent build failures have plagued me. I moved over to CircleCI and haven’t really looked back. However, to get there I had to configure my Ember Add-ons to build efficiently in that environment. I’ve created this simple gist of my CircleCI configuration to share with any other interested parties.
It is worth noting, when my add-on was Ember-2.12 or lower, it would fail to build on release (2.14), beta (2.15), and canary.
Enjoy.
