Are dashes no longer allowed in Intellij module names? I am getting an error trying to add a new one with a dash, although all my previous modules have dashes in the name

I hate using the UI to add modules, I just modify settings.gradle and add a new folder and build.gradle file.

what I do: use underscore instead, then use refactor > rename, and you can use dash (still inside A.S)... kinda stupid 😕
