Independently hit the same issue: https://github.com/Collaborne/web-component-shards/tree/improvement/cli-exit-code-on-error

There is also another place that "eats" errors, and I think that one should be fixed as well: https://github.com/Collaborne/web-component-shards/tree/improvement/no-silent-error, maybe we can join this one into this PR?

@ankon glad we're both running into the same issues! :)

If it's cool with you, I'd rather keep these as 2 separate PRs... I'm a big fan of small, safe changes that fix a very specific problem. It'll probably make each of them more likely to get accepted and merged as well!

Closing due to age.
