Download

Here is a .jar file with run files .sh and .cmd
Also you need to download JavaFx.

Run

To run the .jar do not forget to write VM OPTIONS

--module-path ${PATH_TO_FX} --add-modules javafx.controls,javafx.graphics

Sometimes it requires to write the path to JavaFx by itself, and not take it from PATH_TO_JAVAFX

As content option .sh

export PATH_TO_FX="/opt/javafx-sdk-11.0.2/lib
java —module-path %PATH_TO_FX% —add-modules javafx.controls,javafx.graphics -Dfile.encoding=UTF-8 
-jar /home/vara/idea_projects/virtualpiano/course_work/out/artifacts/course_work_jar/course_work.jar 

Another option if .jar is near to .sh

java --module-path /opt/javafx-sdk-11.0.2/lib --add-modules javafx.controls,javafx.graphics -jar course_work.jar

To run .jar program .jar must be near to .sh, or write the path

/bin/bash startPiano.sh
