Ich folgte den Anweisungen hier http://seleniumhq.org/docs/03_webdriver.html#chrome-driver

Aber ich bin immer der Fehler "Auswahl enthält keine main Typ" am laufen Selenium2Example.java als Java-Anwendung.

Hier ist die pom.xml ich bin mit

Hier ist die Selenium2Example.java ich bin mit:

package org.openqa.selenium.example;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.Chrome.ChromeDriver;
import org.openqa.selenium.support.ui.ExpectedCondition;
import org.openqa.selenium.support.ui.WebDriverWait;

public class Selenium2Example  {
    public static void main(String[] args) {
        //Create a new instance of the Chrome driver
        //Notice that the remainder of the code relies on the interface, 
        //not the implementation.
        WebDriver driver = new ChromeDriver();
        //And now use this to visit Google
        driver.get("http://www.google.com");
        //Alternatively the same thing can be done like this
        //driver.navigate().to("http://www.google.com");
        //Find the text input element by its name
        WebElement element = driver.findElement(By.name("q"));

        //Enter something to search for
        element.sendKeys("Cheese!");
        //Now submit the form. WebDriver will find the form for us from the element
        element.submit();

        //Check the title of the page
        System.out.println("Page title is: " + driver.getTitle());

        //Google's search is rendered dynamically with JavaScript.
        //Wait for the page to load, timeout after 10 seconds
        (new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() {
            public Boolean apply(WebDriver d) {
                return d.getTitle().toLowerCase().startsWith("cheese!");
            }
        });
        //Should see: "cheese! - Google Search"
        System.out.println("Page title is: " + driver.getTitle());        
        //Close the browser
        driver.quit();
    }
}
