Maven测试不使用Selenium Webdriver打开Chrome浏览器

Question

我已经用TestNG for selenium webdriver（Chrome浏览器）创建了一个Maven项目。我用TestNG运行了一个基本测试，Chrome浏览器成功打开。Buf如果我用“Maven test”命令运行相同的测试，我会得到一条错误消息。

你能帮忙吗？我尝试了许多解决方案，如堆栈溢出所建议的，但仍然不成功：（

我已经创建了testng.xml文件

我已经为Selenium-Java和Selenium-Server依赖项以及Chromedriver和SureFire插件使用了不同的版本，但问题仍然存在，现在我对所有这些都使用了最新的版本（更多细节请参见下面的POM文件）。

我已经卸载和重新安装了谷歌Chrome，现在我有了最新的73版

POM文件出现在下面

欢迎光临。

org.openqa.selenium.WebDriverException: Timed out waiting for driver server to start. 

这表示ChromeDriver无法启动新的chrome浏览器会话。

请将您的java更新到最新版本（根据消息，我们可以看到您正在运行java.version:'1.8.0_201'，这是较旧的版本，请考虑更新到最新的java版本11.0）

考虑直接执行一个@test以确保环境良好，然后使用testng.xml进行进一步的执行。
