Jfoenix: Cannot import com.jfoenix.controls.*

[MikeChav]

IntelliJ returns that it cannot import class or package at line
<?import com.jfoenix.controls.*?>

Compiling a simple code returns

The demo runs fine, and regular JavaFX projects run fine. My team mate also got the same issue on his machine.

i believe that jfoenix.jar is not included in the project build path. Make sure it's included in your build path.
