Question

There are a couple of questions to this topic already, but none of them seem to work properly.

Here is a list of them:

• Bulding an multi-platform SWT ap

Answer 1

Right, so I finally came up with a solution that I successfully tested on three platforms.

The two magic components are the jar-in-jar-loader and a proper build script.

The build script with comments can be found here:

What it basically does is define a base classpath without any SWT library. Then it creates platform specific classpaths using the base one and adding the appropriate platform SWT library.

The jar task then creates a separate jar for each platform using these classpaths and the jar-in-jar-loader.

And that's it, a fully automated way of generating jars for each (supported) platform.

I've created an example project that people can download and test out. It's an easy starting point for a multi-platform application.

Update:

I've managed to significantly shorten the ant script by making proper use of macrodef :)
