I encountered exactly the same issue, using the same tutorial today. I was happy to discover I was not alone having the same problem!
Anyway, I tried the solution posted on this other post and it worked for me:
<a href="https://stackoverflow.com/questions/28303723/could-not-find-or-load-main-class-org-testng-testng">could not find or load main class org.testng.TestNG</a>

In other word, the working command line for me is:

<pre><code>java -cp ".;C:\TestNG\testng-6.8.jar" org.testng.TestNG testng.xml
</code></pre>

Hope this will help you!

I have been working on Ubuntu 15.04 and faced a similar problem. 
I used maven to install testng. The advantage was it installed all the dependencies along with it. If you are not using maven, then along with testng jar, download jcommander and beanshell jar files as well. 

When executing the class files after compilation provide the classpath of the following:

<ol>
<li>testng jar</li>
<li>jCommander jar</li>
<li>beanshell jar</li>
</ol>

This is the command I used on my system to run the same example code as mentioned on TutorialsPoint:

<pre><code>java -cp /home/phantom/TestNg\ tutorialsPoint/Programming1:/usr/share/maven-repo/org/beanshell/bsh/2.0b4/bsh-2.0b4.jar:/usr/share/maven-repo/com/beust/jcommander/1.35/jcommander-1.35.jar:/usr/share/maven-repo/org/testng/testng/6.9.5-SNAPSHOT/testng-6.9.5-SNAPSHOT.jar org.testng.TestNG testng.xml
</code></pre>

Programming1 is the directory where my <code>.java</code> and <code>.class</code> files are stored.

blocks|key|2618073|text|有两种方法可以解决上述problem.In下面提到的答案，根据您的setup.Before更改路径，在命令提示符下执行以下命令，确保所有selenium+jars和TestNG+jars都在lib文件夹中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2618074|First+way:+java+-cp+java+org.testng.TestNG+testng.xml|offset|length|style|BOLD|2618075|set的第二种方式：(在和类路径之间提供空格)|2618076|set+classpath=C:\Users\urscomputer\workspace\JenkinsIntegration\lib*;C:\Users\urscomputer\workspace\JenkinsIntegration\bin;|2618077|java+testng.xml|unordered-list-item|2618078|

Two ways are available to solve above problem.In Below mentioned answers change path according to your setup.Before executing the below command in command prompt make sure all selenium jars and TestNG jars should be in the lib folder.

First way:
java -cp C:\Users\urscomputer\workspace\JenkinsIntegration\lib*;C:\Users\urscomputer\workspace\JenkinsIntegration\bin; org.testng.TestNG testng.xml

Second way:(Provide space between set and classpath)

<ol>
<li>set classpath=C:\Users\urscomputer\workspace\JenkinsIntegration\lib*;C:\Users\urscomputer\workspace\JenkinsIntegration\bin;</li>
<li>java org.testng.TestNG testng.xml</li>
</ol>

blocks|key|1924414|text|这似乎与JUnit依赖项/jars有关。将您的junit版本更改为3.8.1并构建您的工作区，它将正常工作|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1924415|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

It seems to be issue with JUnit dependency/jars. Change your junit version to 3.8.1 and build your workspace, it will work

I am following this tutorial <a href="http://www.tutorialspoint.com/testng/testng_environment.htm" rel="nofollow">http://www.tutorialspoint.com/testng/testng_environment.htm</a>

When I enter the command:

<pre><code>java -cp "C:\TestNG_WORKSPACE" org.testng.TestNG testng.xml
</code></pre>

I get the error below:

<pre><code>Error: Could not find or load main class org.testng.TestNG
</code></pre>

Anyone know why? much appreciated.
