I'm trying to execute my testng.xml file from main method using the code below. But getting a NoClassDefFoundError. Any idea what may have caused this issue?
public static void main( String[] args )
{
TestNG testng = new TestNG();
List<String> suites = Lists.newArrayList();
suites.add("testng.xml");
testng.setTestSuites(suites);
testng.run();
}
Exception in thread "main" java.lang.NoClassDefFoundError: org/testng/TestNG
at com.automation.app.App.main(App.java:21)
Caused by: java.lang.ClassNotFoundException: org.testng.TestNG

I was able to fix this issue by using "maven-assembly-plugin" and "maven-dependency-plugin", Then creating the manifest.mf file in resources/meta-inf folder and adding the following information.
Manifest-Version: 1.0
Class-Path: .
Main-Class: {PROVIDE THE MAIN CLASS HERE}
