[java] how to setup intellij idea multi language project
I don't think there is a way of doing that.
You'll probably have to import the maven project and then add the rest of the folders, yourself, configure the correct plugins, etc.
At least that's what I do in a couple of projects where I have Java and Python source files in the mix.
Sometimes, it works even better to simply define different modules for the different types of "sub-project", especially when it's a whole different language and you happen to need to setup a compiler etc, I've ran into some problems with IntelliJ not recognizing my Python modules correctly when I mixed them up in a Java project. All went well when I created a separate module.
Thanks in advance!
