Jar file is not recognized by Maven causes NoClassDefError (ALICE program ab)

Question

Please read the note below.

I am having a problem in my chatbot program. I already did all the instructions they said on the tutorials of different website about how to create a chatbot in java using aiml. I create a maven project. Add the Ab.jar file in the dependency, even in local repository but still I am having this error.

Exception in thread "main" java.lang.NoClassDefFoundError: org/alicebot/ab/MagicBooleans
    at com.Chatbot.main(Chatbot.java:21)
Caused by: java.lang.ClassNotFoundException: org.alicebot.ab.MagicBooleans
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    ... 1 more

This is the half of the code in Chatbot.java

import java.io.File;

import org.alicebot.ab.Bot;
import org.alicebot.ab.Chat;
import org.alicebot.ab.History;
import org.alicebot.ab.MagicBooleans;
import org.alicebot.ab.MagicStrings;
import org.alicebot.ab.utils.IOUtils;

public class Chatbot {
    private static final boolean TRACE_MODE = false;
    static String botName = "super";

    public static void main(String[] args) {
        try {

            String resourcesPath = getResourcesPath();
            System.out.println(resourcesPath);
            MagicBooleans.trace_mode = TRACE_MODE;
            Bot bot = new Bot("super", resourcesPath);
            Chat chatSession = new Chat(bot);
            bot.brain.nodeStats();
            String textLine = "";

It seems that my jar file is not recognized or what. Im actually new to this. Response is a great help.

Note: I have already read some of the NoClassDefError question here in stackoverflow and do what they suggest but still the problem exist.

Did not see any solution here, so here's my solution:

I installed the Ab.jar file into my maven local repository:

mvn install:install-file -Dfile='path to jar file' -DgroupId=Ab -DartifactId=com.google -Dversion=0.0.4.3 -Dpackaging=jar -DgeneratePom=true

Then added the dependency with scope compile (default scope is compile):

<dependency>  
    <artifactId>com.google</artifactId>    
    <groupId>Ab</groupId>    
    <version>0.0.4.3</version>  
</dependency>
