5. Startup class configuration:

5.1. Added javafx-sdk startup parameter configuration

--module-path
"D:\java\install\openjfx-17.0.7_windows-x64_bin-sdk\javafx-sdk-17.0.7\lib"
--add-modules
javafx.controls,javafx.fxml

5.2. Import Artifacts dependencies (all files under javafx-sdk-17.0.7\bin):

6. Command reference for converting jar to win executable exe file:

jpackage --type exe --input . --dest . --main-jar .\[你打的jar包] --main-class [你工程的包名.启动类]p --module-path "[你的javafx-jmods路径]" --add-modules javafx.controls,javafx.fxml --win-shortcut --win-menu
