java.lang.NoClassDefFoundError - Log4j doesn't work even with jar files

I've added log4j-api-2.13.0.jar:log4j-core-2.13.0.jar to CLASSPATH but still I get the following error. Any idea how to resolve the error?
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/logging/log4j/LogManager

ENV:
CLASSPATH=".:selenium-chrome-driver-3.12.0.jar:selenium-server-standalone-3.13.0.jar:guava-13.0.1.jar:junit4.jar:log4j-api-2.13.0.jar:log4j-core-2.13.0.jar"
BASH:
java demo.selenium.IBanTest

Figured it out.
I also had to include log4j2-2.3.jar.
log4j-core-2.14.1.jar
log4j2-2.3.jar
log4j-api-2.14.1.jar
CLASSPATH for example would be like:
CLASSPATH = ".:/home/user/:selenium-chrome-driver-3.12.0.jar:selenium-server-standalone-3.13.0.jar:guava-13.0.1.jar:junit4.jar:log4j-core-2.14.1.jar:log4j2-2.3.jar:log4j-api-2.14.1.jar"
And run the program in directory target/classes/:
java demo.selenium.IBanTest

Add required jar to classpath like this:
For *nix-like systems:
export CLASSPATH=<path-to-app>/myapp.jar:<path-to-app>/lib/json.jar:.
java MyApp
For Windows:
set CLASSPATH=<path-to-app>/myapp.jar;<path-to-app>/lib/json.jar;.
java MyApp
...or via manifest:
Manifest-Version: 1.0
Main-Class: MyApp
Class-Path: /lib/json.jar

How do I know which jar files java program needs to run?

Recently I was trying to run 2048 bot (upd: author deleted the project, but created the new one). But it just didn't work. And the developer said that it runs from Intelij IDEA just fine. And yes, it appeared it does. So what I did:
>"c:\Program Files\Java\jdk1.7.0_51\bin\javac.exe" Program.java -cp selenium-java-2.41.0.jar
Note: Program.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
>java Program -cp selenium-java-2.41.0.jar
Error: Could not find or load main class Program
Intelij IDEA runs it this way:

So it starts with jdk's jar files, then goes the project output directory, then some jar files, which are probably downloaded by Intelij IDEA on its own and it ends with the Intelij IDEA's jar file, which is probably needed for debugging or something along those lines.
So, how do I know which jar files are needed and where do those ~/.m2 files come from?
UPD Here are probably the minimal jar files set to start this program:
C:\Users\Yuri\.m2\repository\org\seleniumhq\selenium\selenium-firefox-driver\2.39.0\selenium-firefox-driver-2.39.0.jar
C:\Users\Yuri\.m2\repository\org\seleniumhq\selenium\selenium-remote-driver\2.39.0\selenium-remote-driver-2.39.0.jar
C:\Users\Yuri\.m2\repository\org\json\json\20080701\json-20080701.jar
C:\Users\Yuri\.m2\repository\org\seleniumhq\selenium\selenium-api\2.39.0\selenium-api-2.39.0.jar
C:\Users\Yuri\.m2\repository\com\google\guava\guava\15.0\guava-15.0.jar
C:\Users\Yuri\.m2\repository\org\apache\httpcomponents\httpclient\4.3.1\httpclient-4.3.1.jar
C:\Users\Yuri\.m2\repository\org\apache\httpcomponents\httpcore\4.3\httpcore-4.3.jar
C:\Users\Yuri\.m2\repository\commons-logging\commons-logging\1.1.3\commons-logging-1.1.3.jar
C:\Users\Yuri\.m2\repository\org\apache\commons\commons-exec\1.1\commons-exec-1.1.jar
So it's not all the jar files even in m2 diretory.
UPD Selenium Client & WebDriver Language Bindings comes with additional jar files but not all of them are needed. So one of the options was to specify all these jar files. But I was able to make it work this way:

UPD Alternatively:
find -name '*.jar' -execdir cp -t ~/path/to/prj {} +

If you compile
javac Program.java
then Program.class will be generated. This must be in your classpath.
java -cp "Program.class;selenium-java-2.41.0.jar"

A Java program does not need any specific jar files to run, but it need the contained classes.
There are various tools and sites to help you find out:
How to find Jar to which an Java class belongs
There are also tools to help you manage those dependencies, like Maven (.m2 is related to it).
The author states that
You will need to install the Selenium dependency somehow, such as by using Maven.
IMHO the project should come with a pom.xml or the jars.

Could not find the main class: org.junit.runner.JUnitCore. Program will exit.
What is the problem?

org.junit4.9b2.junit.SimpleTest
