Question

所以在我编译了我的selenium代码并运行file.class之后我得到了以下错误

org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:

我使用以下命令在Jenkins master上运行代码

javac -cp selenium-java-2.53.0.jar:selenium-java-2.53.0-srcs.jar:selenium-server-standalone-2.53.0.jar myfile.java

echo $USERNAME 
echo $PASSWORD 
echo $CLUSTERNUM 
echo $IPADD

java -cp .:selenium-java-2.53.0.jar:selenium-java-2.53.0-srcs.jar:selenium-server-standalone-2.53.0.jar myfile $USERNAME $PASSWORD $CLUSTERNUM $IPADD

使用此代码块启动Firefox驱动程序

System.setProperty("webdriver.gecko.driver", "C:\\your_directory\\geckodriver.exe");
DesiredCapabilities capabilities=DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
WebDriver driver = new FirefoxDriver(capabilities);
driver.get("http://www.google.com"); 
driver.quit();

在jenkins主节点上运行时，Selenium错误“无法在45000 ms后在端口7055上连接到主机127.0.0.1”
