Simple JavaFX to merge PDF files.

Maven version: 3.8.7
Java version: 17
JavaFX version: 17.0.9

The jar file which is built with mvn clean package command is a fat jar. If your OS supports launching applications with double-click, then this is how you execute the jar file.

If you need more sophisticated ways then use below instruction

java -jar PdfMerger.jar

Or turbo complex way. Once the jar file is built with mvn clean package then with following assumptions:

1. %J17% - is the path the Java 17 home directory.
   
2. %JFX17% - is the path to the libs directory from JavaFX 17.0.9 framework.
   
3. PdfMerger.jar is the jar file that should be executed.
   

below command launches the program:

%J17%\bin\java --module-path %JFX17% --add-modules=javafx.fxml,javafx.controls,javafx.media,javafx.web,javafx.swing --add-exports=javafx.base/com.sun.javafx.event=ALL-UNNAMED --add-opens=javafx.graphics/javafx.scene=ALL-UNNAMED -jar "PdfMerger.jar"
