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: could not find or load main class org.testng.TestNG
我遇到了完全相同的问题，今天使用相同的教程。我很高兴地发现并非只有我有同样的问题！无论如何，我尝试了在另一篇文章中发布的解决方案，它对我有用： 找不到或加载主类 org.testng.TestNG
In other word, the working command line for me is:
换句话说，我的工作命令行是：
java -cp ".;C:\TestNG\testng-6.8.jar" org.testng.TestNG testng.xml
Hope this will help you!
希望能帮到你！

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.
我一直在 Ubuntu 15.04 上工作并遇到了类似的问题。我使用 maven 来安装 testng。优点是它安装了所有依赖项。如果您不使用 maven，那么除了 testng jar 之外，还要下载 jcommander 和 beanshell jar 文件。
When executing the class files after compilation provide the classpath of the following:
编译后执行类文件时，提供以下类路径：
- testng jar
- jCommander jar
- beanshell jar
- 测试罐
- jCommander jar
- 豆壳罐
This is the command I used on my system to run the same example code as mentioned on TutorialsPoint:
这是我在系统上使用的命令，用于运行 TutorialsPoint 上提到的相同示例代码：
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
Programming1 is the directory where my .javaand .classfiles are stored.
Programming1 是存放 my.java和.classfiles的目录。

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.
有两种方法可以解决上述问题。在下面提到的答案中，根据您的设置更改路径。在命令提示符下执行以下命令之前，请确保所有 selenium jar 和 TestNG jar 都应在 lib 文件夹中。
First way:java -cp C:\Users\urscomputer\workspace\JenkinsIntegration\lib*;C:\Users\urscomputer\workspace\JenkinsIntegration\bin; org.testng.TestNG testng.xml
第一种方式：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)
第二种方式：（在set和classpath之间提供空间）
- set classpath=C:\Users\urscomputer\workspace\JenkinsIntegration\lib*;C:\Users\urscomputer\workspace\JenkinsIntegration\bin;
- java org.testng.TestNG testng.xml
- set classpath=C:\Users\urscomputer\workspace\JenkinsIntegration\lib*;C:\Users\urscomputer\workspace\JenkinsIntegration\bin;
- java org.testng.TestNG testng.xml

It seems to be issue with JUnit dependency/jars. Change your junit version to 3.8.1 and build your workspace, it will work
这似乎是 JUnit 依赖项/jar 的问题。将您的 junit 版本更改为 3.8.1 并构建您的工作区，它将起作用
