title: FileUtils not showing suggestion to import predefined class for Screenshot functionality in selenium WebDriver
body: <p>I am not allowed to use FileUtils in the program and error is shown when doing so. Even no suggestion is showing to import this pre-defined Class. I tried to search the solution but what I found was to import the class. But in my case even suggestion is not showing to import any class. Hovering on the "FileUtils" shows the suggestion to create FileUtils class/interface. Below is my code:</p>
  
  <pre><code> package captureScreenshot;
  
  import java.io.File;
  import java.io.IOException;
  
  import org.apache.commons.io.FileUtils; //Getting Error at this line
  import org.openqa.selenium.By;
  import org.openqa.selenium.OutputType;
  import org.openqa.selenium.TakesScreenshot;
  import org.openqa.selenium.WebDriver;
  import org.openqa.selenium.firefox.FirefoxDriver;
  import org.testng.annotations.Test;
  
  import com.google.common.io.Files;
  
  public class FacebookScreenshot {
  
  @Test
      public void captureScreenshot() throws IOException
  {
      WebDriver driver = new FirefoxDriver();
      driver.manage().window().maximize();
      driver.get("https://www.facebook.com");
      driver.findElement(By.xpath("//input[@name='firstname']")).sendKeys("Anil Kumar");
  
      TakesScreenshot ts = (TakesScreenshot) driver;
      File source = ts.getScreenshotAs(OutputType.FILE);
      FileUtils.copyfile(source,new File("./Screenshots/facebook.png")); //Getting error at this line
  
      driver.quit();
  
      }
  
  }
  </code></pre>
