Missing log4j dependency for SURF with scala/sbt about jfeaturelib

[locked-fg]

HI, just tested it with plain Java and a call from the commandline

public class SurfDemo {

    public static void main(String[] args) throws IOException, URISyntaxException {
        // load the image
        InputStream stream = SurfDemo.class.getClassLoader().getResourceAsStream("test.jpg");
        ColorProcessor image = new ColorProcessor(ImageIO.read(stream));

        // initialize the descriptor
        SURF descriptor = new SURF();

        // run the descriptor and extract the features
        descriptor.run(image);

        // obtain the features
        List<double[]> features = descriptor.getFeatures();

        // print the features to system out
        for (double[] feature : features) {
            System.out.println(Arrays2.join(feature, ", ", "%.5f"));
        }
    }
}

Works without errors. Any Idea? Otherwise I tend to think it's a sbt issue,

Thanks for confirming it's working as expected I will try to switch to Java and report back :)

It's working like you said. So it seems related to sbt / scala..

I've updated the repo jFeatureLib examples to fix some issues and add the surf demo there:
locked-fg/JFeatureLib-Demo#1

@locked-fg I'm opening it again as I can reproduce the issue in my repo: https://github.com/samos123/scala-feature-extraction

When using maven to build the scala project everything works as expected but when using sbt it fails with the log4j class not found exception.

I will be sticking with Maven for now but may investigate more into this later on. Any feedback would be appreciated :)

Thanks for your energy in that point. I'm trying to find a colleague who's willing to invest some energy ( @muuki88 - if you feel bored, feel free to join ;-)
