What I did was "create a project from existing source" in Eclipse (gave it the path to the demo folder), imported the Lucene jar file and ran the application. As far as I can tell, the only required library is the Lucene jar file (I was using 1.9, but that shouldn't matter).
I freely admit that the things I don't know about building Java application are many, but if you're building other Java applications, this should follow a familiar pattern and build easily in whatever your favorite development environment is. Best Erick
