If I add the external libraries (which can be found in the libs folder), I get the error:

Exception in thread "main" java.lang.NoSuchMethodError: org.numenta.nupic.Parameters.set(Lorg/numenta/nupic/Parameters$KEY;Ljava/lang/Object;)V

mvn clean install

is successful with two warnings and 1 error:
