net.thucydides.core.webdriver.UnsupportedDriverException：无法实例化类org.openqa.selenium.firefox.FirefoxDriver

Question

我使用mac mojave 10.14.3，JDK 1.8，Serenity core 2.0.40（最新）来开发我的测试用例。使用Chrome版本，它们都能很好地运行。 73（100％的时间）或Firefox版本。在我的本地mac系统上有65.0（99％的时间）。我们的Jenkins运行在没有GUI的Redhat linux上。我们安装了Firefox浏览器（Firefox版本60.5.0可能是最新版本），因为RH Linux不支持/不可用Chrome。当我合并代码并要求我的管理员在Jenkins上运行git分支时，我总是会遇到错误。

我在我的项目代码中有这些：Selenium-java：3.141.59

Selenium-api：3.141.59

Selenium-server：3.141.59

geckodriver：0.24.0

chromedriver：2.45.615355

今天在每次测试运行100％传递我的本地Mac系统后，运行Jenkins（RH Linux盒子）我收到此错误（运行2次）。

*********可能是一个BUG ????? **

 According to this page, [Serenity BDD Book]https://serenity-bdd.github.io/theserenitybook/latest/web-testing-in-serenity.html 

我准备我的config.properties文件为...

Chrome浏览器无头测试

    webdriver.driver=chrome
    headless.mode = true
    drivers.windows.webdriver.chrome.driver = 
       src/test/resources/webdriver/windows/chromedriver.exe
    drivers.mac.webdriver.chrome.driver = 
       src/test/resources/webdriver/mac/chromedriver
    drivers.linux.webdriver.chrome.driver = 
        src/test/resources/webdriver/linux/chromedriver

Firefox浏览器无头测试

      webdriver.driver=firefox
      gecko.firefox.options = {"args": ["-headless"]}
      drivers.mac.webdriver.gecko.driver = 
         src/test/resources/webdriver/mac/geckodriver
      drivers.linux.webdriver.firefox.driver = 
         src/test/resources/webdriver/linux/geckodriver

但是我遇到了上面报告的问题UnsupportedDriverException：我需要说，一切都在我的本地Mac系统上完美运行，但不适用于使用Firefox浏览器60.5版本的RedHat Linux机器（应该与geckodriver 0.24.0配合使用）

但我们的Jenkins系统管理员将geckodriver添加到系统路径，然后它工作了!!!!!我们的Jenkins服务器在RedHat Linux上运行。
