Executable Jar with Eclipse & Libgdx

Question

This is the first time I have tried to create an executable jar file from Eclipse, and I am confused as to how to do so. I know that there is the option to export a java file as a "jar" and "executable jar", but I am not sure how to ensure that my libgdx libraries, assets, and HighScore.txt file are fully integrated and are working. Furthermore, like most packages my package has a myriad of classes - one of which is the main class. How do I export the jar files and instruct eclipse that this specific class is the main class. Here is an image of my file structure:

MainSimpleBike is my main class.

Answer 1

1. Using the default jar

   You specify your main class during runtime, like:

   java -jar MyJar.jar MainSimpleBike
   

2. You may also modify the manifest.txt by following the instruction here:

   http://docs.oracle.com/javase/tutorial/deployment/jar/appman.html

   If you modify the manifest.txt, like:

   Main-Class: com.me.mygdxgame.MainSimpleBike
   

   To create a jar:

   jar cfm MyJar.jar Manifest.txt com.me.mygdxgame/*.class
   

   You can simply run:

   java -jar MyJar.jar
   

   Your main class will be picked up automatically.
