IntelliJ: Autocopy folder content to an IntelliJ folder

I have a question, which seemed easy at the beginning when I started working on it but I could not find an easy solution for it so far. Is there a way to auto copy content from a folder to a current folder in my IntelliJ project?

Away from IntelliJ, this can be done programmatically; and I will need to add a file watcher to observe changes and apply them accordingly. Alternatively, I can create a scheduled task to do this. However, I am inclined to avoid this as there must be an easy way to do this.
