Htmlunitdriver conflicting with Rest Assured API

Question

I am trying to use Htmlunitdriver but it looks like it is conflicting with Rest Assured API.

If i remove rest assured library from the pom.xml, the below code works fine HtmlUnitDriver driver = new HtmlUnitDriver();

If i add rest assured library to the pom.xml, an exception is thrown as below:

Below is the list of dependencies

<dependencies>
<dependency>
    <groupId>org.testng</groupId>
    <artifactId>testng</artifactId>
    <version>6.8.1</version>
 </dependency>        
       <dependency>
    <groupId>com.jayway.restassured</groupId>

Not sure how to get around with this. I tried to use different Selenium version (2.24.1) and it resolved the exception. But it is giving me problems with the webpage i am trying to access. Also if i create a Java project and add the selenium and rest assured jars, i dont see any problem.

I believe something to do with Maven dependency.

I found a resolution for this - Adding below code to the pom file resolved the issue -

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
            <version>4.5.1</version>
        </dependency>
        <dependency>
            <groupId>commons-io</groupId>
            <artifactId>commons-io</artifactId>
            <version>2.4</version>
        </dependency>
    </dependencies>
  </dependencyManagement>

Basically Selenium HTML Unit required a higher version of the above dependencies so adding this code will serve the purpose.
