Having issue with pom.xml - eclipse

Question

I am trying to integrate Selenium TestNG to maven but having trouble in adding dependencies to pom.xml (as described in this article ), and getting error on the same. Issue appears only when I add selenium and testng dependencies, I have already imported those library to the project. Below is xml code
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<dependency>

<artifactId>testng</artifactId>
<version>6.9.5</version>
<scope>test</scope>
</dependency>
</dependencies>
</project>
And this is the error I am getting
As suggested in some articles I cleaned the project, refreshed but nothing worked out.
I am a newbie to Maven so will be very greatfull for all helpful suggestion on how to fix this.

Answer 1

Issue resolved by removing dependencies, there was no need to add dependencies. Maven adds them automatically.
