If the main jar is in a subfolder the .cfg file is written incorrectly leading to: Error: Could not find or load main class <fully-qualified class name> Caused by: java.lang.ClassNotFoundException: <fully-qualified class name>
Which I only found by manually running: ./MyApp.app/Contents/MacOS/MyApp as double clicking doesn’t seem to show that output anywhere (I tried to find it in the Console.app output, but didn’t). In my case the main jar is in a ‘libs’ subfolder. The image is built correctly, with the subfolder under the ‘Java’ folder in the Mac application bundle. However, the cfg file had: app.mainjar=MyMainJar-1.0.0.jar instead of: app.mainjar=libs/MyMainJar-1.0.0.jar When I manually made that edit, it started to work.
