Pessoal eu executei o primeiro código utilizando o chromedriver da mesma forma que na aula porem os seguintes erros foram apresentados, ja aconteceu isso com alguem ?

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

public class TesteAutomatizado {

    public static void main(String[] args) {
        System.setProperty("webdriver.chrome.driver", "\\Desktop\\Renan\\Alura\\Selenium\\chromedriver.exe"); 

        WebDriver driver = new ChromeDriver();

        driver.get("http://www.google.com.br/");

        WebElement q = driver.findElement(By.name("q"));

        q.sendKeys("Caelum");

        q.submit();
