问题描述

我正在尝试使用页面工厂和页面对象模型运行 Java 项目，我想在 Chrome、IE 和 Firefox 上运行它，但我无法在 Firefox 上运行它，浏览器没有打开，我我收到此错误:java.lang.NoClassDefFoundError: org/w3c/dom/ElementTraversal

I am trying to run a Java project using page factory and page object model, I want to run it on Chrome, IE and on Firefox, but I am not able to run it on Firefox, the browser is not opening, I am getting this error : java.lang.NoClassDefFoundError: org/w3c/dom/ElementTraversal

我的代码是:

@BeforeMethod
public static void openBrowser() {
    String browser = "";
    if (browser.equalsIgnoreCase("chrome")){
        System.setProperty("webdriver.chrome.driver", "src\\test\\Resources\\BrowserDrivers\\chromedriver.exe");
        driver = new ChromeDriver();
    }
    else if (browser.equalsIgnoreCase("ie")){
        System.setProperty("webdriver.ie.driver", "src\\test\\Resources\\BrowserDrivers\\IEDriverServer.exe");
        driver = new InternetExplorerDriver();
    }
    else {
        driver = new FirefoxDriver();
    }
    driver = new FirefoxDriver();
    driver.get("http://www.google.com/");
    driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
    driver.manage().window().maximize();
}

@AfterMethod
public  static void closeBrowser(){
    driver.quit();
}

推荐答案

参见例如这个 Github issue，一些依赖项可能会拖入过时可能导致此问题的 xml-apis 版本，对我有用的解决方案是添加对 xml-apis 的特定依赖项，例如与 Maven 类似

See e.g. this Github issue, some dependencies can drag in an outdated version of xml-apis which can cause this, a solution that worked for me was to add a specific dependency on xml-apis, e.g. with Maven something like

<dependency>
    <groupId>xml-apis</groupId>
    <artifactId>xml-apis</artifactId>
    <version>1.4.01</version>
</dependency>
