I got this error then I created #15 because I thought adding the LICENCE.md file would fix it.

But in the error above you can see "dev-add-license-1" has the same problem.

AFAICT https://github.com/acquia/reservoir-project/blob/8.1.x/composer.json#L5 is the thing you need to change to fix this error.

@tedbow @wimleers The new version 1.0.0-alpha5 is still not showing up in Packagist. 🤕 What does the error message say?
