At least the AWSSDK repository now gives an composer.lock error, because the change rEAWK8a394dd0e82a39aa451fd1ba4aba1a1dc7fda974 only updates the composer.json, not the also commited composer.lock file.
20:00:25 + composer --ansi validate --no-check-publish
20:00:28 ./composer.json is valid, but with a few warnings
20:00:28 See https://getcomposer.org/doc/04-schema.md for details on the schema
20:00:28 The lock file is not up to date with the latest changes in composer.json, it is recommended that you run composer update.
20:00:28 No license specified, it is recommended to do so. For closed-source software you may use "proprietary" as license.
Please check all repositories with composer.lock file, if the lock file needs changes to unbreak CI
