I test the following HelloCV code of opencv3.0.0 with Java Eclipse neon and I got the error "could not find or load main class". How can I solve this?

package againtest;

import org.opencv.core.Core; import org.opencv.core.CvType; import org.opencv.core.Mat;

public class HelloCV { public static void main(String[] args){ System.loadLibrary(Core.NATIVE_LIBRARY_NAME); Mat mat = Mat.eye(3, 3, CvType.CV_8UC1); System.out.println("mat = " + mat.dump()); }

}

Try running just that specific file, not the whole project if you have several files in the project. It might be that Eclipse. Itself has decided which file should be main.
