Not able to run selenium jar file using testng.xml from command line

I am trying to run a Selenium Java Test (jar file) build on Gradle using TestNG.xml from the command.

Note: I am able to successfully run the test case from IntelliJ.

But when I package the project in a .jar file and try to run it from the CLI (Windows 11 powershell), its throwing an error.

On running the Below code

java -cp untitled-0.1-all.jar org.testng.TestNG Testng.xml

Getting this error:

[main] ERROR org.testng.TestNG - Cannot find class in classpath:com.xyz.Test1

Project Structure and Code.

Test1 Class Code:

Its a simple test class opens up chrome browser using selenium and verifies title of the page.

package com.xyz;import com.google.common.util.concurrent.Uninterruptibles;import io.github.bonigarcia.wdm.WebDriverManager;import org.openqa.selenium.WebDriver;import org.openqa.selenium.chrome.ChromeDriver;import org.testng.Assert;import org.testng.annotations.Test;import java.time.Duration;public class Test1 {    @Test    public void test() {        System.out.println(">>>>>>>>>>>>> Starting the test");        //Opening the Chrome brower        WebDriverManager.chromedriver().setup();        WebDriver driver = new ChromeDriver();        //Opening google page and verifying the title        driver.get("https://www.google.com");        Uninterruptibles.sleepUninterruptibly(Duration.ofSeconds(10));        String actualTitle = driver.getTitle();        Assert.assertEquals(actualTitle, "Google");        //Close the chrome browser        driver.quit();        System.out.println(">>>>>>>>>>>>> Ending the test");    }}

Testng.xml

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd"><suite name="Suite"><test name="Test"><classes><class name="com.xyz.Test1" /></classes></test></suite>

build.gradle

plugins {    id 'java'    id 'java-library'    id 'com.github.johnrengelman.shadow' version '8.1.1'}group = 'xyz'version = '0.1'repositories {    mavenCentral()}shadowJar {    // Include test resources    from 'src/test/resources'    // Include test code    from 'src/test/java'}dependencies {    //Add impementation & testImplementation as was not sure if this was the source of problem.    implementation 'org.seleniumhq.selenium:selenium-java:4.26.0'    implementation 'org.testng:testng:7.10.2'    implementation 'org.slf4j:slf4j-simple:2.0.9'    implementation 'io.github.bonigarcia:webdrivermanager:5.8.0'    testImplementation 'org.testng:testng:7.10.2'    testImplementation 'org.seleniumhq.selenium:selenium-java:4.26.0'    testImplementation 'io.github.bonigarcia:webdrivermanager:5.8.0'}jar {    manifest {        attributes 'Main-Class': 'com.xyz.Test1'    }}test {    useTestNG()}

From the powershell (Windows 11) ran the following commands:

> gradle clean> gradle shadowJar

Then ran the below command

> java -cp .\build\libs\untitled-0.1-all.jar org.testng.TestNG .\src\test\resources\Testng.xml

Getting this error

[main] ERROR org.testng.TestNG -Cannot find class in classpath: com.xyz.Test1

I have further checked the .Jar file and it contained the com.xyz.Test1 Class (screenshot below for reference)
