java - Selenium SouceLabs - java.lang.NoClassDefFoundError : org/apache/commons/codec/binary/Base64

Question

我用 Cucumber-jvm 和 selenium webdriver 构建了一个 UI 自动化框架，为了跨浏览器测试，我有 selenium 网格，它在本地成功执行，但是当我将 selenium 网格指向 soucelabs 网格时，它会抛出以下错误，

我之前搜索过这个错误，建议的解决方案是在 Maven 中添加 commons-codec jar 文件的依赖项，我这样做了，但仍然遇到了同样的问题。

任何帮助都非常感谢，因为我一直坚持这个。

我解决了我的问题，感谢 @Paweł Głowacz 的指点，我没有使用 apache commons 编解码器版本 10，而是将其更改为版本 9，这解决了我的问题。
