External jars not found while running the application

Question

In my project, I have some external jars. So I added those jars in project libs folders also.

I refer : https://www.tutorialspoint.com/maven/maven_external_dependencies.htm

If I am running my project in eclipse so it is working as expected but when I created .jar file and tried to ran through .bat file it gave me throws me error.

1. APIFactory.class is present in one of my external jar file.

2. I think the problem present in maven packaging due to that jar was not includes in executable jar file. But I tried and search so many nut I didn't got any specific answers.
