Since commit 683793d the AppVeyor CI tests are failing for PHP versions >= 7.2 on the staging branch.
AppVeyor CI tests succeed.
AppVeyor CI tests fail.
The "error" message "Your Composer dependencies require a PHP version ">= 5.3.10" and "< 7.2.0". You are running ..." at the bottom of each log is misleading, is also comes when a build has run with success.

We might try here: https://github.com/joomla/joomla-cms/blob/staging/.appveyor.yml#L132
composer install --ignore-platform-reqs ?
And see whether it is a workaround.
What do you think @rdeutz
As my proposed fix does not fix the issue i have just closed the PR so this Issue here should stay open to track the issue. So someone who has more knowledge with appveyor can take a look here. Thanks.
