Attempting to execute Selenium IDE exported code and getting this runtime error: Exception in thread "main" java.lang.NoSuchMethodError: main

Question

My end goal is to confirm that I have Java, Selenium WebDriver, and JUnit functioning such that I can run an automated test case utilizing these technologies.

What I have done so far:

1. installed Selenium IDE (v 2.8.0) for Firefox (v 34.0.5)
2. recorded a simple test case using Selenium IDE and added the test case to a test suite
3. in Selenium IDE exported the test case using the option: File->Export Test Case As...->Java / JUnit 4 / WebDriver
4. downloaded and installed JUnit 4 from: https://github.com/junit-team/junit/wiki/Download-and-Install (Plain-old jar method)
5. downloaded and installed Selenium client and WebDriver Java language binding (v 2.44.0) from: http://www.seleniumhq.org/download/
6. performed some slight modifications to the code generated in step 3 such as removing the package statement at the beginning
7. compiled the code with the following command (windows command prompt):

C:\docs\tech\code\myCode\java\testing\selenium\utest\practice>C:\java\jdk\bin\javac.exe -cp C:\docs\installs\programming\automation\test\xUnit\java\jUnit\junit\v4_12\junit-4.12.jar;C:\docs\installs\programming\automation\test\xUnit\java\jUnit\hamcrest\hamcrest-core-1.3.jar;C:\docs\installs\programming\automation\web\selenuim\webdriver\java\selenium-2.44.0\selenium-java-2.44.0.jar C:\docs\tech\code\myCode\java\testing\selenium\utest\practice\TestGooglePlayApp.java

this compiles with no warnings/errors

8. attempt to execute the code with the following command:

C:\docs\tech\code\myCode\java\testing\selenium\utest\practice>java -cp .;C:\docs\installs\programming\automation\test\xUnit\java\jUnit\junit\v4_12\junit-4.12.jar;C:\docs\installs\programming\automation\test\xUnit\java\jUnit\hamcrest\hamcrest-core-1.3.jar;C:\docs\installs\programming\automation\web\selenuim\webdriver\java\selenium-2.44.0\selenium-java-2.44.0.jar TestGooglePlayApp

Actual Result:

The output of this attempt is:

Exception in thread "main" java.lang.NoSuchMethodError: main

No other error/warning is given and no indication is given that the code begins to execute

Expected Result:

This is my first time interacting with these technologies so I'm learning as I go! However, based on the research I have done my expectation is that a local Selenium WebDriver instance will be initialized as a Firefox Driver. This Firefox Driver will be sent instructions by the Java code in order to carry out the steps in the test case. JUnit will then indicate somehow on the command line the Pass/Fail status of the test case.

The big assumption I have here is that the Selenium Server/Selenium RC is not required in this case since all I intend to do is execute a local Selenium WebDriver script. Furthermore, my hope is that this can be launched directly from the command-line independent of Eclipse, Maven, etc. I would like to be able to send the final Java class to a colleague and the only dependency for expected execution would be a working SDK of Java on the end machine.

What's Next?

I'm looking for advice on what I can do to get this code up and running under the restraints I have outlined. It may be that the code needs to be modified. It may be that my expectations need to be tempered down and it's just not possible to do everything I want directly from the command-line. It may be that I did not compile the code correctly or some library is missing. It may be that... okay you get the point!
