Genetic algorithm main: correct Lucene versions.

[andrea patricelli]

Hi,

I'm trying to use genetic algorithm on my database, but I'm facing a lot of problems with dependencies.
I'm using Duke 1.2 and I'm using Maven.
Is

<dependency>

      <groupId>no.priv.garshol.duke</groupId>

      <artifactId>duke</artifactId>

      <version>1.2</version>

</dependency>

enough? Probably not because I get:

I tried to add Lucene dependencies (4.0.0 referencing [1]), and 4.1.0 (because the error is "speaking"), but got other class not found errors.
What is the minimal set of dependencies that I've to use?

Best regards,
Andrea
