I have a unique situation here. I am using the third party SDK 19.fx-librca. This SDK contains the javaFX jars. I am doing this because it makes it easier to create .dmg, .msi, .rpm packages. I only have one issue. I cannot launch my program from a run configuration.
It has been explained to me that I need to go to Preferences -> Tools -> Shared Indexes and set JDK's to don't download, because the intellij shared indexes don't include JavaFX for Java 19.
I then went to File -> Invalidate Caches, then checked all the checkboxes and then clicked the "invalidate and Restart" button.
This is not working for me as I am still getting all the "package javafx.* does not exist" errors. This does work fine when I use Eclipse, so I know it is an Intellij thing. My question is if there is a work around for this?
