答

此错误消息...

java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkState(ZLjava/lang/String;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)V

...表示执行该行时出现错误:

...implies that there was an error raised while executing the line:

System.setProperty("webdriver.chrome.driver", "/ocs/browserDrivers/chromedriver.exe");

您的主要问题是 WebDriver 二进制类型与基础操作系统之间的不兼容性.

Your main issue is the incompatibility between the WebDriver binary type and the underlying Operating System.

您需要从

Linux操作系统:

Linux OS:

chromedriver_linux64.tar.gz 2018-09-13 19:30:37 3.85MB

MAC OS:

chromedriver_mac64.tar.gz   2018-09-13 18:14:11 5.75MB

Windows操作系统:

Windows OS:

chromedriver_win32.zip  2018-09-13 21:11:33 3.42MB

如果您使用的是 MAC OS ，则System.setProperty()行应为:

If you are using MAC OS so the System.setProperty() line would be:

System.setProperty("webdriver.chrome.driver", "/ocs/browserDrivers/chromedriver"); //drop the extension (.exe) part

如果您使用的是 Windows操作系统，则System.setProperty()行应为:

If you are using Windows OS so the System.setProperty() line would be:

System.setProperty("webdriver.chrome.driver", "C:\\path\\to\\chromedriver.exe"); //mention the absolute path
