使用 selenium web 驱动程序运行测试 - NoClassDefFoundError

Question

我试图弄清楚如何工作 - selenium web 驱动程序。

并尝试运行简单的程序，但在控制台发现下一个错误：

java.lang.NoClassDefFoundError: selenium/web/driver/Selenium2Example
Caused by: java.lang.ClassNotFoundException: selenium.web.driver.Selenium2Example
    at java.net.URLClassLoader$1.run(Unknown Source)
    at java.security.AccessController.doPrivileged(Native Method)
    at java.net.URLClassLoader.findClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClassInternal(Unknown Source)
Exception in thread "main" 

和带有消息的弹出窗口：

Could not find the main class, program will exit

我在 Windows XP 下使用 Eclipse Helios。
我为 progect 附加了 neded -jars（ selenium-java-2.35.0 + selenium-server-standalone-2.35.0 ）。

这是代码：

public class Selenium2Example {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // Create a new instance of the Firefox driver
        // Notice that the remainder of the code relies on the interface,
        // not the implementation.
        WebDriver driver = new FirefoxDriver();
        // 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();
    }

}

我不明白为什么这找不到主类...

更重要的是它无法将可执行文件.class创建到bin文件夹中。

有什么建议吗？

• 为什么会发生这种情况以及如何解决这个麻烦？

删除 selenium 独立 jar 并将selenium-java-2.33.0-srcs.jar 、 selenium-java-2.33.0.jar 添加到 lib 并作为java 应用程序运行
