带有 maven 的 Selenium 无法检测到没有 maven 可以检测到的 webelements答案

【问题标题】：Selenium with maven cannot detect webelements it was able to detect without maven带有 maven 的 Selenium 无法检测到没有 maven 可以检测到的 webelements

【问题描述】：

我已将我的 selenium TestNG 项目转换为 maven，并在同一个 webelement 上编写了相同的命令，在非 maven 版本中检测到对象，但在 maven 版本中找不到它（java.lang.NoClassDefFoundError）

这是命令：

                        // Define Ad
                        wait.until(ExpectedConditions.visibilityOfElementLocated
                                (By.cssSelector("span.close.js-rebateHook")));
                        WebElement Ad_X = driver.findElement(By.cssSelector("span.close.js-rebateHook"));
                        
                        // Closes ad if exists
                        if (Ad_X.isDisplayed()) {
                            //act.doubleClick(Ad_X).perform();
                            Ad_X.click();
                            System.out.println("Closed Ad");
                        }
                        else {
                            ;
                        }

这是 maven 运行时的控制台结果：

[ERROR] Logo_Exsists(testcases.OpenZafulTest)  Time elapsed: 7.9 s  <<< FAILURE!
java.lang.NoClassDefFoundError: org/openqa/selenium/interactions/Coordinates
    at testcases.OpenZafulTest.Logo_Exsists(OpenZafulTest.java:53)
Caused by: java.lang.ClassNotFoundException: org.openqa.selenium.interactions.Coordinates
    at testcases.OpenZafulTest.Logo_Exsists(OpenZafulTest.java:53)

这是非 maven 运行的控制台结果（打印，也关闭了广告）：

Closed Ad

这是我的 pom.xml（此时非常混乱，我被困在这个问题上很长一段时间，并根据我在网上看到的许多示例尝试添加、删除和更改我的许多依赖项）：

如果有人知道这个问题的原因或如何解决它，那将有很大帮助

【问题讨论】：

你是如何运行测试的？单纯的跑课？还是 mvn 命令？
我用“Run as maven test”运行 pom.xml，它引用了 testng.xml 文件
尝试一次 mvn clean 和 mvn compile。
现在试了，没有任何变化，同样的问题又发生了
所以你没有看到任何编译问题..当你运行测试时粘贴完整的控制台异常。它与你的 Maven 配置相关。找不到那个类

标签： java html selenium maven selenium-webdriver

【解决方案1】：

您的项目在转换时损坏了，右键单击该项目，转到 maven 并更新该项目

【讨论】：

我已经更新了did the maven>更新项目，很多次都没有解决
好的，如果没有看到你的实际项目，这将很难说，参考这个可能会有所帮助 - javarevisited.blogspot.com/2011/06/…。
