Execute runnable jar cross os

[Darius Boteand]

Hi!

This is a tricky task, but I am trying to run a runnable jar across different OSs.
I know that this task is possible should you already have installed eclipse or anything supporting java.

Now how about a system without any IDE.  Is there a way of perhaps embedding something within the jar that will make it run?
Or perhaps I should use a portable IDE on a USB stick?

How would you do this if you were me?

first: java -jar some-filename.jar - it's the same accross all os as long as java is in the path
second: you don't need a full IDE - just the JRE is enough

Check out jlink. It was added in Java 9, and allows you to make smaller Java installations that contain only the modules that you need.
