[SOLVED] Allure/TestNG/Maven: org.testng.ITestNGListener: Provider io.qameta.allure.testng.AllureTestNg could not be instantiated

I am trying to integrate Allure to my Maven project. Here's what I've done so far: - Installed a commandline and set up the class path. As part of validation when I run allure --version in a console, I get a 2.4.1 back. - I followed the instructions at https://docs.qameta.io/allure/latest/#_testng and made changes to the POM as mentioned there. Here's my POM:

But when I clean test, I get the below error:

I checked online for solution and I ran into this page: https://github.com/allure-framework/allure-maven/issues/13 And from the comments it seemed like an issue with my class path but not sure how to pin point the problem.

I tried clean test by commenting out the below dependency and my build succeeds and a sure-fire report is generated.

<dependency>
    <groupId>io.qameta.allure</groupId>
    <artifactId>allure-testng</artifactId>
    <version>2.0-BETA19</version>
    <scope>test</scope>
</dependency>

And I am able to generate an Allure report using the command line: allure serve ...\surefire-reports

Please let me know what I am doing wrong. Thanks!
