Usage: <main class> [options]
Options:
-browserTimeout
<Integer> in seconds : number of seconds a browser session is allowed to
hang (0 means indefinite) while a WebDriver command is running (example:
driver.get(url)). If the timeout is reached while a WebDriver command is
still processing,
the session will quit. Minimum value is 60. Default is 0
-debug
<Boolean> : enables LogLevel.FINE. Default is false (if omitted)
Default: false
-jettyThreads, -jettyMaxThreads
<Integer> : max number of threads for Jetty. Default is 200
-log
<String> filename : the filename to use for logging. If omitted, will log
to STDOUT
-port
<Integer> : the port number the server will use. Defaults to [4444]. When
"role" is a set to [node], default is [5555]
Default: 4444
-role
<String> options are [hub], [node], or [standalone] : Default is
[standalone]
Default: standalone
-timeout, -sessionTimeout
<Integer> in seconds : Specifies the timeout before the server
automatically kills a session that hasn't had any activity in the last X
seconds. The
test slot will then be released for another test to use. This is typicall
y
used to take care of client crashes. For grid hub/node roles, cleanUpCycl
e
must also be set. Default is 1800 (30 minutes)
Default: 1800

所以我下载了必要的jar文件并执行了以下命令 java -jar selenium-server-standalone-2.28.0.jar [替换为下载的最新版本]
获取如下消息：要做什么？

这些是您可以应用的几个步骤，无论是否有效
）下载selenium独立jar文件。
2）粘贴到lib文件夹中的jar文件中。
3）project-＆gt; properties-＆gt; java build path-＆gt;添加jar-＆gt;选择独立的jar文件 - ＆gt;点击确定
4）运行 - >外部工具 - ＆gt;外部工具配置 - ＆gt;新配置。
5）为java.exe和selenium standalone server.jar
添加位置和工作目录6）点击变量并将Argument添加为-jar selenium-server-standalone-3.0.1.jar
7）点击申请并运行....
8）在Eclipse控制台中，您将获得端口号，这将确认您启动了selenium独立服务器

启动硒时遇到同样的问题。我通过杀死占用端口4444的进程解决了这个问题。
netstat -aon | findstr 4444
然后你可以得到占据4444端口的pid xx。taskkill /T /F /pid xx
