Hello source forge community.
Recently i donwloaded neuroph 2.9 framework.
I implemented the jar file "neuroph-core-2.94.jar" in my netbeans editor.I created a neural network but when i try to call

package up;    

import org.neuroph.core.NeuralNetwork;
class AI3 {
public static void main(String args[]){
NeuralNetwork nn=new NeuralNetwork();
}
}

It throws an Exception

Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
    at org.neuroph.core.NeuralNetwork.<init>(NeuralNetwork.java:106)
    at up.AI3.main(AI3.java:5)

Project misses some loggin dependencies.
If you use gradle you can inpoert thme like that
compile'org.slf4j:slf4j-api:1.7.22'
compile group: 'ch.qos.logback', name: 'logback-classic', version: '1.2.3'
compile group: 'ch.qos.logback', name: 'logback-core', version: '1.2.3'

or import them in any other suitable for you way
