Issue

Unable to double-click / run the command java -jar duke-0.2.jar for the JAR file that I had created using gradlew shadowJar . I am only able to right-click the JAR file and run it in IntelliJ.

I had added and removed the dependencies according to #72.

There's no error in all the steps. The JAR file just doesn't work. Why?

Code/Log Trace

Executing `gradlew run' works:

Running java -jar duke-0.2.jar command:

Right-clicking JAR file in Intellij works:

Remove the following lines from your build.gradle

id 'org.openjfx.javafxplugin' version '0.0.7' //javafx (line 6)
and
javafx { version = "11.0.2" modules = [ 'javafx.controls', 'javafx.fxml' ] } (line 23-27)
they are no longer required as the JavaFX dependencies will be specified by lines 43 - 60 instead (you can also optionally choose to remove line 55 - 60 as they are unnecessary).

Your jar file generated by shadowJar should then be able to run on any system.

However, I noticed another bug during testing - your program won't launch if the file data/duke.txt is not present. You might want to look into ways to create the file automatically instead of throwing an exception and closing - see #27

Hope that helps! :)
