How to use global arguments for Java in vscode?
I am trying to setup my JavaFX enviroment so I referenced the corresponding Jars. In order to run the code I need to use some VM Arguments (“vmArgs”: ” –module-path /Users/adrif/Downloads/javafx-sdk-14.0.2.1/lib –add-modules javafx.controls,javafx.fxml”) in the launch.json.

Java Invalid maximum heap size
