[Solved] Export a (libgdx) project to jar file with Eclipse

Newbie & Debugging Questions
#1

Whenever I try export my game (which works fine in Eclipse) to a runnable JAR file, it will not create a runnable JAR file, just a folder containing the projects data. Any ideas what I’m doing wrong?

I have tried following methods in Eclipse:

File->Export->Runnable JAR file->Extract required libaries into generated JAR.
File->Export->Runnable JAR file->Package required libaries into generated JAR.

with launch configuration:
DesktopLauncher - “game”-dektop.

But I just can’t get it as a runnable JAR file.

The way I do it is sort of incorrect I was told, so I’ll tell you another good method. Putting everything in a zip file. Have your resource folder in there too. I think you just export as a runnable jar, then use jarSplice to put in your libraries. once you create the fat jar, then you put it in the zip folder. I’m not 100% sure this works the same for libGDX.

Also, if you’re having trouble running the jar, try starting it with cmd. In cmd input

cd desktop

press enter

java -jar ThenameOfyourProject.jar

It should tell you any errors it finds.

#3

Silly question but do you add the .jar to the file name where it asks where to save the file?

#4

Thanks, the JarSplice made it work with a breeze!

#5

You should try: Right Click Desktop project -> Export -> Pack required libraries into jar file.

Maybe eclipse does different things when doing File -> Export and Project -> Export, since the latter works for me.

#6

Am I allowed to re-open this?

Looks like you were successful. What’s the latest on this topic? I know Eclipse has gone through a lot of changes since the last post here.
