WebDriver出错

Question

我有以下错误：

Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkState(ZLjava/lang/String;Ljava/lang/Object;)V
    at org.openqa.selenium.remote.service.DriverService.checkExecutable(DriverService.java:136)
    at org.openqa.selenium.firefox.GeckoDriverService.access$000(GeckoDriverService.java:41)
    at org.openqa.selenium.firefox.GeckoDriverService$Builder.usingFirefoxBinary(GeckoDriverService.java:134)
    at org.openqa.selenium.firefox.FirefoxDriver.toExecutor(FirefoxDriver.java:155)
    at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:120)
    at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:98)
    at automationFramework.SecondTest.main(SecondTest.java:20)

我的代码：

package automationFramework;

import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.remote.DesiredCapabilities;

import junit.runner.Version;
public class SecondTest {

    public static void main(String[] args) throws Exception {



        System.out.println("JUnit version is: " + Version.id());

    DesiredCapabilities capabilities = DesiredCapabilities.firefox();
    capabilities.setCapability("marionette", true);

    FirefoxDriver driver = new FirefoxDriver();


    //System.setProperty("webdriver.gecko.driver", "C:\\\\Program Files\\Firefox Developer Edition\\firefox.exe");  
    System.setProperty("webdriver.gecko.driver", "E:\\\\Projects\\WebDriver\\geckodriver.exe"); 

    driver.get("http://www.google.com");




    }

}
