I copied some folders to src folder (before start IDEA) but IDEA cannot recognize them. I need to open Project Structure dialog then expand src node. At this time, IDEA will display new folders.
I tried to close IDEA, remove a subfolder in src folder then open IDEA. IDEA still display the removed folder. And I can open files in removed folder. Only when I open Project Structure dialog then expand src node, this time IDEA will update src folder's content.
But if I copy/remove folders while IDEA is running, IDEA can recognize the changes.
Does anyone see it?
