Support for `@css-blocks/ember-cli`

👋 Hi all!

I would like to host some runnable ember twiddle examples of CSS Blocks in an Ember app. However, when I add @css-blocks/ember-cli to twiddle.json the application hangs with a perpetual “Building…” message.

Looking at old issues, it appears this happens when https://github.com/joostdevries/twiddle-backend has trouble building an ember addon. I tried to pull down the project and spin up my own instance of it to see where the addon build is failing, but couldn’t get it running – docker image dies with:

Step 17/23 : COPY addon-build-configs/$EMBER_VERSION/ember-cli-build.js /addon-builder/ember-cli-build.js
COPY failed: stat /var/lib/docker/tmp/docker-builder986033965/addon-build-configs/2.9.0/ember-cli-build.js: no such file or directory

l’Il keep poking at the docker image, but figured I’d open an issue here as well to see if anyone can easily help me debug.

Okay! Update. Finally got the docker image working locally, was able to reproduce my bug and fix it in @css-blocks/ember-cli@0.23.2. I can now run the docker image against that version and see it build properly with no error. However, when I update the version in https://ember-twiddle.com/57b20467d824add6364cc47b3727d2dc, the build still hangs.

Before I go through the rigamarole of setting up ember-twiddle itself for development to debug more, can you take a peek in the uploaded modules and verify that @css-blocks/ember-cli@0.23.2 built and uploaded properly, and this is a frontend build problem, not a module build problem?
