Create a multi-platform executable for the SWT application (Eclipse)

I have an Eclipse based SWT application not using Maven.

My application is designed for several operating systems (CentOS, Windows and Mac).

The only jar file that is not OS agnostic is the SWT library, which is specific to each type of OS, not to mention the type of processor (x86 and / or x64).

I saw this other problem , but it concerns Maven, and I do not use Maven.

I have "org.eclipse.swt" added to my project following the procedure described and including the entire downloaded SWT zip file. This indicates the second project in the package explorer.

Previously, when I just turned on swt.jar, it was a little easier, because I just needed to remove the jar, turn on the new one and rebuild, but it was painful. Now that I use the whole SWT ZIP, the process is a bit tedious and not professional.

What are the steps, so when I specify "right click> Java> Runnable JAR file" to create a single executable jar, I get 3 (or as many) different jar files, one for each operating system? Visual Studio does it beautifully, I just don’t know how to do it in Eclipse.
