@starraven if you need another short-term patch, we used to have an Ember app that listed how to get those files on the main Ember website. From what I remember, those files were produced until 3.0 or 3.4. In theory, if you check out this repo at this commit (Merge pull request #156 from jenweber/lts-notes · ember-learn/builds@0c1a7a4 · GitHub) you might be able to go back in history and see what the old
/builds page listed about how to retrieve those files (I think they were up in an S3 bucket).
But yes, Chris’ answer is the long-term best approach, the whole community is moving / has been moving to Ember-CLI since about Ember 1.12 days, so best to join us using that if at all possible
Edit: tracked down one link to the last version of Ember 2.18, urls follow a predictable schema here, so in theory you can get the right version of the file that you need. Not sure about template compiler and ember data though, but those should be traceable if you decide to go that route: http://builds.emberjs.com/tags/v2.18.0/ember.prod.js
