title: class "org.hamcrest.Matchers"'s signer information does not match signer information of other classes in the same package
body: <p>I am getting the following message while running my java program. I see lots of suggestions to remove the JUNIT and try which works perfectly fine but impacting my RunnerClass(Below) at the same time. There are suggestions given in other posts but apparently none seems to be working in my case. Any assistance will be really appreciated.</p>
  
  <p>RunnerClass:-</p>
  
  <pre><code>package HybridFrameWork;
  
  import org.junit.runner.RunWith;
  import cucumber.api.CucumberOptions;
  import cucumber.api.junit.Cucumber;
  
  @RunWith(Cucumber.class)
  @CucumberOptions(features="src\\test\\java\\HybridFrameWork", glue={"HybridFrameWork"},plugin="html:reports")
  public class RunnerFile {
