Folked This project from https://github.com/dpearson/Hex
Improved beta-alpha search tree with multiple heuristics function to evaulat future board state.
You'll need a few dependencies; these include a JDK, make, and zip. I've only tested the code on Java 6, although both the OpenJDK and the Sun one work.
Then, just run:
make jar
java -jar Hex.jar
