Problem running jar file

I am trying to run milk-1-0.jar file from this website. I have jre installed and set my classpath using: set CLASSPATH=C:\Users\chudy\Desktop\Work\wekafiles\milk\milk-1-0.jar . When I am trying to run the file from a command line using java milk.classifiers.DD -t data.arff according to this file http://www.cs.waikato.ac.nz/~ml/milk/README I am getting following error message:

Exception in thread "main" java.lang.NoClassDefFoundError: milk/classifiers/DD
