Java SessionNotCreatedException:无法创建新服务：Ubuntu上带有Selenium网格的Geckodriverse无法驱动Firefox

我无法用geckodriver从Selenium驱动Firefox。这很奇怪，因为chrome是用相同的框架驱动的，没有错误

以下是我的版本号：

Firefox 54.0 (64-bit)
Chrome Version 62.0.3202.94 (Official Build) (64-bit)

selenium-server-standalone-3.7.1.jar
client-combined-3.5.3-nodeps.jar

geckodriver-v0.19.1-linux64
chromedriver_linux64 

Ubuntu 16.10

我从Selenium webdriver with java中得到的错误如下：

--------------------------------Error:
leder@leder-VirtualBox:~/Source/SeleniumCheese/bin$ ./execute_grid.sh 
Exception in thread "main" org.openqa.selenium.SessionNotCreatedException: Unable to create new service: GeckoDriverService

这是我的设置，firefox已损坏，chrome正常：

Grid_SetUp.java

package de.auticon.selenium_server;
import org.openqa.selenium.WebDriver;    
import org.openqa.selenium.By;   
import org.openqa.selenium.WebElement;   
import org.openqa.selenium.remote.DesiredCapabilities;    
import org.openqa.selenium.remote.RemoteWebDriver;
import java.net.MalformedURLException;    
import java.net.URL;

public class Grid_SetUp {   
    public static WebDriver driver;

    public static void main(String[]  args) throws MalformedURLException, InterruptedException{   
        System.setProperty("webdriver.chrome.driver","/opt/selenium/chromedriver");    
        String URL = "http://www.google.de";    
        String Node = "http://192.168.40.40:4444/wd/hub";    
        DesiredCapabilities cap = DesiredCapabilities.firefox();   
        driver = new RemoteWebDriver(new URL(Node), cap);
        driver.navigate().to(URL);
        WebElement element = driver.findElement(By.name("q"));
        //Enter something to search for
        element.sendKeys("Cheese!");
        // Now submit the form. WebDriver will find the form for us from the element
        element.submit();
        // Check the title of the page
        System.out.println("Page title is: " + driver.getTitle());

        Thread.sleep(5000);

        driver.quit();    
    }    
}

selenium_grid.sh：

#!/bin/bash
java -jar /opt/selenium/selenium-server-standalone-3.7.1.jar -role hub &
java -Dwebdriver.gecko.driver=/opt/selenium/geckodriver -jar /opt/selenium/selenium-server-standalone-3.7.1.jar -role webdriver -hub http://192.168.40.40:4444/grid/register -nodeConfig /opt/selenium/defaultNodeConfig.json -browser "browserName=firefox,platform=LINUX" &

执行_grid.sh：

#!/bin/bash
java -cp ".:/opt/selenium/selenium-server-standalone-3.7.1.jar" de.auticon.selenium_server.Grid_SetUp

我现在更新了工作配置的问题。但是，当运行firefox Selenium TC时，TC完成，不幸的是，服务器以错误消息“会话未创建”结束：

关于

Selenium Grid

配置的几句话：

• 您提到您的

  试验台

  为

  selenium-server-standalone-3.7.1.jar

  和

  client-combined-3.5.3-nodeps.jar

  。根据

  最佳实践

  ，您应该使用以下两种方法之一

• 始终尝试使用最新发布的版本，即selenium-server-standalone-3.7.1.jar

• 在

  selenium\u grid.sh:

  中，您需要更改以下内容：

  java -Dwebdriver.gecko.driver=/opt/selenium/geckodriver

我使用我的firefox浏览器seleinum grid和eclipse中的Testng简单地遵循这段代码

System.setProperty("webdriver.gecko.driver","E:\\FireFoxDriver\\geckodriver.exe");    
    String URL = "http://demo.automationtesting.in/Register.html";    
    String Node = "http://192.168.43.97:4444/wd/hub";    
    DesiredCapabilities cap = DesiredCapabilities.firefox();   
    driver = new RemoteWebDriver(new URL(Node), cap);
    driver.get(URL);
    driver.manage().window().maximize();
    System.out.println("Page title is: " + driver.getTitle());

    Thread.sleep(5000);

    driver.close(); 

用于在本地计算机中创建集线器 java-jar E:\SeleniumGrid\selenium-server-standalone-3.141.59.jar-角色中心

打开cmd并在下载selenium独立服务器的行上方输入 然后你会得到这两个

节点应注册到 客户端应连接到

然后再次打开cmd并为节点键入此命令

java-Dwebdriver.gecko.driver=“E:\FireFoxDriver\geckodriver.exe“-jar E:\SeleniumGrid\selenium-server-standalone-3.141.59.jar-角色节点-hub

谢谢你，DebanjanB！我可以省去

：/opt/selenium/client-combined-3.5.3-nodeps.jar

，而

java-Dwebdriver.gecko.driver=/opt/selenium/geckodriver

现在运行良好！我将问题更新为工作配置，并添加了新的错误消息，请查看。@DebanjanB基于，最新版本为3.141.59，我使用该版本，但不提供帮助。

System.setProperty("webdriver.gecko.driver","E:\\FireFoxDriver\\geckodriver.exe");    
    String URL = "http://demo.automationtesting.in/Register.html";    
    String Node = "http://192.168.43.97:4444/wd/hub";    
    DesiredCapabilities cap = DesiredCapabilities.firefox();   
    driver = new RemoteWebDriver(new URL(Node), cap);
    driver.get(URL);
    driver.manage().window().maximize();
    System.out.println("Page title is: " + driver.getTitle());

    Thread.sleep(5000);

    driver.close();
