错误：无法访问org.openqa.selenium.HasInputDevices,找不到类文件

Question

我跑：

mvn clean test

我得到了这个错误：

https://seleniumhq.github.io/selenium/docs/api/java/org/openqa/selenium/interactions/hasinputdevices.html

看来是我的FirefoxDriver或ChromeDriver导致了这个问题。

下面是我的pom.xml文件：

您之所以会出现此错误，是因为pom.xml中的依赖项不兼容。
依赖项列表应如下所示。
