lwjgl-packaging

Goal

A gradle.build script demonstrating the packaging of an LWJGL-dependent project as either a standalone jar or a Windows executable.

The "Space Invaders" demo LWJGL program is included so as to provide a full-fledged sample.

Tasks

The following Gradle tasks are available:

run: build an application jar and run it. Mostly useful to ensure everything is in place.
myCapsule: build a standalone jar: build/libs/[ProjectName]-capsule.jar.
launch4j: build a Windows executable: build/launch4j/[ProjectName].exe.

Both the jar and executable can be launched "as is". In particular, the Capsule framework takes care of setting up java.library.path so as to link to the native LWJGL libraries.

Using this Script to Package your Code

Copy build.gradle at the root of your project.
Ensure that your project layout follow maven/gradle conventions (code in src/main/java, resources in src/main/resources).
If under Eclipse, convert your project to a Gradle one (see "Eclipse setup" below).
At least adjust the value of mainClass, have a look at other variables.
Use myCapsule or launch4j task to package your code.

I did not add the MIT license at the beginning of the script to keep things simple, but if you use it please consider making a reference to this project page if at all reasonable.

Eclipse Setup

To test this under Eclipse:

Install Eclipse Gradle tooling.
"Import as general project" from Git Repositories view.
Right click on project, "Configure > Convert to Gradle Project".
Try "Ctrl+Alt+Shift+R > run" to ensure that the project is properly set up.

Acknowledgements

This script builds upon the Capsule, gradle-capsule-plugin, gradle-natives and launch4j tools.

It ships with the "Space Invader" LWJGL example game, on which I do not claim any right.
