java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property

Question

package com.merchantPlatform;

import java.util.concurrent.TimeUnit;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.remote.DesiredCapabilities;

public class MerchantPlatformTest {

    public static void main(String[] args) {

        System.getProperty("webdriver.gecko.driver", "C:\\Selenium WebDriver\\geckodriver\\geckodriver-v0.17.0-win64\\geckodriver.exe");

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

        // Initialize WebDriver
        WebDriver driver = new FirefoxDriver(capabilities);

         /* This works fine for versions lesser than Selenium 3. For Selenium 3 and higher, it will throw java.lang.IllegalStateException */

        // Maximize Window
        driver.manage().window().maximize();

        // Wait For Page To Load
        driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);

        // Navigate to MerchantPlatform URL
        driver.get("http://localhost:52939/");

    }

}

Error

I am getting the below exception with System.getProperty

Exception in thread "main" java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property; for more information, see https://github.com/mozilla/geckodriver.

Solution 1

You have to use System.setProperty not the System.getProperty as follows.

System.setProperty("webdriver.gecko.driver",
                "C:\\Selenium WebDriver\\geckodriver\\geckodriver-v0.17.0-win64\\geckodriver.exe");

Solution 2

I have noticed that you are using wrong syntax, to opening the browser.

Instead of using System.getProperty, You have to use System.setProperty as mentioned below.

System.setProperty("webdriver.gecko.driver", "C:\\Selenium WebDriver\\geckodriver\\geckodriver-v0.17.0-win64\\geckodriver.exe");

Thanks.. It was setProperty, works fine now.. I tried to mark both your answers correct, but unable to do.. Though I searched a lot for this error, I missed the set part.
