I've been using tornadofx with jdk11 using a gradle build and suddenly yesterday it stopped being able to run the app in intellij or with `gradle run` . That seemed like a bug in the javafx gradle plugin -- the error message was because it was running with `--module-path` that had no arguments. I managed to solve it by downloading openjfx 11 and setting `sdk =  'javafx-sdk-11.0.2'` . Now I can build and run the app both directly via gradle and in intellij. HOWEVER, now intellij is red-underlining all javafx references because it can't find the library.

How do I tell intellij where to find the javafx library so that I don't get the underlines and code completion starts working again?

Weird.

I had added the lib to project settings but files were still showing red underlines so I thought I was missing something. But closing and reopening the project seems to have cleared everything up.
