There doesn't seem to be anything wrong with running the jar like this. But it is failing to find the resources it needs. My understanding is that it is looking for the image from the relative file path, not the class path, try copying the image it is loading images/appMenu. png to the relative directory you are running this from. Or run inside the original app bundle context such that the path will be correct, rather than from the desktop. Moving is preferred because there could be other resources loaded at runtime that are missing.

cd /root/Desktop/applicationFramework

java -cp SWT/swtLinux.png:/root/Desktop/mainProject.jar boot.Run
