I took me some time and made this maven repository file for lwjgl 2.2.1.
maven-lwjgl-repository.zip (http://sites.google.com/site/obisoftware/home/files/maven-lwjgl-repository.zip)
The only thing you need to do is unpack the repository in your project then add
<repository>
<id>local.project</id>
<name>local.project</name>
<url>file://${project.basedir}/repository</url>
</repository>
Then just add the lwjgl artifacts. You can see how I handle the native libs in the eclipse sample project below.
This empty project has a pom that lets you run the lwjgl tests with just a few clicks.
1. Run the maven-compile launcher for your platform
2. Refresh the eclipse project.
3. Right click the project and Run As -> Java application then select the test you want to run :)
lwjgl-test.zip (http://sites.google.com/site/obisoftware/home/files/lwjgl-test.zip)
It will fetch the right native files to depending on what profile you run.
Have fun!
