Selenium在Chrome Driver中遇到错误

javaseleniumselenium-webdriverselenium-chromedriver

在本地机器上使用chrome driver运行脚本时，我遇到了以下错误，但是同样的脚本在firefox上运行正常。我正在使用selenium-java 2.48.2和chrome driver 2.20

错误日志..

请添加您的代码，看起来像是jar冲突的问题！！ - Pankaj Kumar Katiyar

似乎有一些jar包的依赖关系被忽略了，或者jar包没有正确下载。 - Mrunal Gosar

我已经检查过所有的依赖项都被正确添加了。 - Shiva Krishna

这是一个依赖问题。项目构建路径中没有添加所需的selenium jar文件。还要检查代码中ChromeDriver.exe路径是否正确指定System.setProperty("webdriver.chrome.driver","chromedriver exe path");。

我遇到了类似的错误，添加以下依赖项解决了这个问题 -

      <dependency>
      <groupId>org.seleniumhq.selenium</groupId>
      <artifactId>selenium-remote-driver</artifactId>
      <version>2.48.2</version>
      </dependency>

浏览调用栈并找到有问题的类帮助我分析出我的当前类版本不是最新的。
