I\'ve just moved from years of using Eclipse to the brave new world of IntelliJ and I\'m trying to iron out the little (trivial) little things that are slowing me down.
Follow these steps:
First set the folder as a "Sources Root" by right clicking and navigating to "Mark directory".
Right click on the same item
Select "New" → "Package"
In my case, I was not able to see the create new package option.
