After trying to create (and then delete) a folder in the src IDEA directory, it stopped recognizing classes and packages as directories, but earlier everything was fine.

Why is this happening and how to fix it?

    You need to mark the src directory as the source of the source code https://www.jetbrains.com/help/idea/2016.2/configuring-content-roots.html Right-click on the src directory - mark directory as "sources"

    The directory should be highlighted in bluish color, by analogy with the "java" directory in your module just below

      Do you specify a module in the main "wizard"? If so, then try to "import" the "maven" changes into ideas. Click on the "filmstrip" icon in the bottom left-hand corner of the idea, various tabs will appear on the side, including "maven". There will be a button "Import chages" or something like that.
