如何从命令行启动.jar文件GUI？

Question

I'm trying to write a quick script to launch a couple of (3rd party) .jar files. Normally I would navigate to the folder and double click the files individually which brings up a GUI.

When I run java -jar [filename].jar it doesn't open the GUI and instead runs as a command line app. Which makes sense I guess.

Is there any way to force it to open the GUI when running on the command line?

I'm using a Mac.

Thanks!

Double clicking on a .jar file on a Mac runs the .jar via an app hidden in a system folder called Jar Launcher.

To simulate the double click from the command line you can run the Jar Launcher and pass it the .jar file as a parameter.

open /System/Library/CoreServices/Jar\\ Launcher.app ~/Path/to/JarFile.jar

No idea why or how the .jar was showing different behaviour from double clicking when running with java -jar but this fixes it (on a Mac at least).
