How to convert a normal java project in intellij into a JavaFx project

Question

I am currently using a normal java project (gradle project) and want to convert this into a JavaFx project without having to reimport the existing sources into a new Javafx

Answer 1

I followed those steps

• Create a new module in your existing intellij project (A)
• Create a new JavaFx project elsewhere
• Copy the code from the JavaFx project, namely Controller.java,Main.java and sample.fxml into your module in the (A) project under the src directory as in A/user-interface/src

• You'll find an error in sample.fxml since it references the controller class as sample.Controller change it to 'Controller' only. it worked this way (as I removed the sample package folder

• In (A) open the settings menu File | Project Structure | Modules
• Select the user-interface module from the list on the left side of the settings window
• Switch to the dependencies tab
• Add your old non-gui module as a module dependency using the green + mark on the right-hand side
• Now you can use the classes in the non-gui module, enjoy!

note: you can skip the add module dependency and let intellij do it for you, just type a name of a class in the old module, alt+enter (the light bulb magic) -> add module depenency
