require_tree ../something works when compression: false even if path is not defined in assets:sources in _config.yml, but the same require_tree is silently ignored when compression: true

Problem with require_tree

Use case:

  sources:
  - _assets/js
  - _assets/css
  - _assets/images
  - _assets/_sass/vendor/dreamhost-css/src/fonts
  # note: _assets/_sass/vendor/dreamhost-css/src/js is not listed here

main.js:

//=require_tree ../_sass/vendor/dreamhost-css/src/js

When compression: false is set, files inside the above directory will be included in the output of main.js.

However, when compression: true is set, this directory will NOT be included in the output of main.js. What's more, it will NOT raise any error during build.

require is not affected

  sources:
  - _assets/js
  - _assets/css
  - _assets/images
  - _assets/_sass/vendor/dreamhost-css/src/fonts
  # note: _assets/_sass/vendor/dreamhost-css/src/js is not listed here

main.js:

//=require ../_sass/vendor/dreamhost-css/src/js/scripts.js

require works as expected. That is, it raises an error.

Only after adding _assets/_sass/vendor/dreamhost-css/src/js to assets:sources makes it pass.

Request

Make require_tree always throw an error if the path where a JS is to be required from isn't listed in assets:sources, just like require.

I feel like this would be a Sprockets issue, all things considered we don't compress, or handle trees, we do indeed handle sources (we pass them into Sprockets) but other than that we don't typically deal with the compression, or the trees and finding assets.

[Nowaker]

I don't know if it's Sprockets or Jekyll-assets, but compression is a documented Jekyll-assets option and it doesn't work properly and is silent about it.

[envygeeks]

We can't be noisy about something we don't handle.

[envygeeks]

Let me rephrase because I don't want you to think I don't care, I do care it's silent, I just don't know why and I feel like this might be a sprockets but, but I do plan on looking into it.
