Unwanted warnings on composer.json in 2020.2 Permanently deleted user Created August 03, 2020 06:25 PhpStorm 2020.2 is giving the warning to remove 'autoload' and 'autoload-dev' properties as it flags them as prohibited.
Can't reproduce that: https://prnt.sc/tudj54
What JSON scheme do you have chosen? You can check that in the status bar.
Also, would File | Invalidate Caches / Restart | Invalidate and Restart help?
