Problem with using Java 11 on Mac [message #1810237]

Howdy,

I'm using Java 11 on Mac and installed e(fx)clipse latest from marketplace into eclipse 2019-6. After creating project, however, the javafx.* classes cannot be imported...i.e. their reference in Main has compile error.

I've seen that Java 11 removed JavaFX from the main distro...is this what's causing this problem? Either way, how is it best fixed with Java 11 on mac?

Scott

Dieter Engelhardt, cmon that's just plain lazy and also that does not provide an answer I've been there. To use anything above Java 8 requires much more (I beleive) unnecessary work and detailed instruction. I tried for two nights to get it working before piecing together the parts from various sources in to one clear and comprehensive instruction. Although, I instruction is written for Windows, I know it also works on a Mac too because I own one and it worked there too. I do this everytime I create a JavaFX project, and its bloody annoying.

Creating a Java FX Project
Go through this step for each new Java FX project to be built. First, go to file > new > other and find the option for creating a new Java FX Project. Once the project is created you will notice it does not compile as Eclipse needs to know about the JavaFX libraries.
Access the project properties and then find the Java build path. Select the Libraries tab and then module path. Then select the add library button and then select the user library option before pressing next.
On the window that appears select new and name the library JavaFX13. Select add external jars and then find the lib folder of your JavaFX 13 installation directory and select all of the .jar folders then apply and close or finish on all windows.
If you attempt to run the project you will find it will not be able to find application.main. To fix this we have one last step. Right click main.java in Eclipse's package explorer. Select run as > run configurations and then select the arguments tab. In the vm arguments add the following (where the module path points to the lib your installation of the Java FX sdk):
--module-path C:\ Java\javafx-sdk-13.0.1\lib --add-modules=ALL-MODULE-PATH
