I just run a simple test with testNG(version 6.8). All code is like this. 

import org.testng.annotations.*;
public class TestNGtest {
    @Test
    public void test(){
        System.out.print("123");
    }
}

I run it but it returns :

Exception in thread "main" java.lang.NoClassDefFoundError: com/beust/jcommander/ParameterException
    at org.testng.RemoteTestNGStarter.main(RemoteTestNGStarter.java:119)
Caused by: java.lang.ClassNotFoundException: com.beust.jcommander.ParameterException
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    ... 1 more

BUT there is jcommander.jar in my classpath（in my java/jre/lib） already. someboby has the same problem?

It is a maven project, i have added jcommander ,testng dependencies in my pom.xml ; these code is all fine when run on other computers ,but only throws this error on my computer(i cloneed it from git). Can anybody help me?

  • There is something wrong with your parameter. Should be **@Test()**. If there is a problem see this link. https://stackoverflow.com/questions/30435688/getting-java-lang-noclassdeffounderror-com-beust-jcommander-parameterexception – Kyaw Kyaw Aug 28 '17 at 05:46

Download jcommander jar file from the maven repository and add it to the dependencies just like testng jar file

Go to projectstructure->Modules->depenencies->add jcommander jar file-> click apply

dependencies in projectStructure
