Missing sourcemaps

I get this error when upgrading to ember-source@2.14.0 and building the app:

Warning: ignoring input sourcemap for vendor/ember/ember.debug.js because ENOENT: no such file or directory ...
Warning: ignoring input sourcemap for vendor/ember/ember-testing.js because ENOENT: no such file or directory, open ...

There are two problems with that:

• the supplied source maps are missing from the build (obviously)
• the warnings break our CI (but this is more related to https://github.com/ef4/fast-sourcemap-concat/issues/35)

I think the reason for this is that the dist files contain a reference to their sourcemap at the end of the file: //# sourceMappingURL=ember.debug.map. This seems to be new for 2.14, at least 2.13 did not have this. While there is a dist/ember.debug.map in the published npm package, these files are not added to the vendorTree in index.js, so they are really missing in the tmp tree when fast-sourcemap-concat tries to read them.

I can put a PR together exporting those files in the vendorTree if that is the way to go? But given there is https://github.com/emberjs/ember.js/pull/15102, I am not so sure about it…

I have the same issue.

Almost a year later, this warning pops up again in my codebase when upgrading from ember-source@3.2.2 to ember-source@3.3.0

The exact warnings are:

Warning: ignoring input sourcemap for vendor/ember/ember.debug.js because ENOENT: no such file or directory, open '<hidden>/tmp/source_map_concat-input_base_path-gcU53ttn.tmp/vendor/ember/index.js.map'
Warning: ignoring input sourcemap for vendor/ember/ember-testing.js because ENOENT: no such file or directory, open '<hidden>/tmp/source_map_concat-input_base_path-VfRaj57E.tmp/vendor/ember/testing.js.map'

Googling about this only led me to this issue.

Has anyone else experienced this?
