Getting Geckodriver error evenif it is defined in code - maven

Question

I am using 2 classes for my basic Maven and Selenium project-openGmail. I am using Selenium 3.5 with Firefox 47.0.1 and Gecodriver 0.18.
My Main class is:
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
public class MainClass {
WebDriver driver = new FirefoxDriver();
public void setup() {
String Path_GecoDriver="C:/Personal/Selenium/setup/geckodriver-v0.18.0-win64";
System.setProperty("webdriver.firefox.marionette", Path_GecoDriver+"/geckodriver.exe");
System.setProperty("webdriver.gecko.driver", Path_GecoDriver+"/geckodriver.exe");
}
public void OpenBrowser() {
String url="http://google.co.in";
driver.get(url);
}
public void LoginGmail() throws InterruptedException {
String username ="username";
String passwd = "passwd";
driver.findElement(By.linkText("Gmail")).click();
driver.findElement(By.id("identifierId")).sendKeys(username);
WebElement cli=driver.findElement(By.xpath("//*[text()='Next']"));
cli.click();
Thread.sleep(1000);
driver.findElement(By.xpath("//input[#name='password']")).sendKeys(passwd);
driver.findElement(By.xpath("//*[text()='Next']")).click();
}
public void CloseBrowser() {
driver.close();
}
}
My other class is:-
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class TestngClass {
MainClass mc=new MainClass();
#Before
public void sp() {
mc.setup();
mc.OpenBrowser();
}
#Test
public void LG() throws InterruptedException {
mc.LoginGmail();
}
#After
public void CB() {
mc.CloseBrowser();
}
}
I am getting the error
java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property; for more information
I have tried to execute it the test by putting my System.setProperty (prop, path/to/driver) in my #Before, and # test also but no change, I am still getting the error.
If I use a single class then everything works fine so I think I am placing my system.setProperty at the wrong place.
I have started with Java and Selenium very recently. I have even tried to put my Gecko driver exe in src/main/resources of my Maven project as mentioned in In System.setProperty("webdriver.gecko.driver", "<Path to your WebDriver>"), what is meant by "Path to your WebDriver"?

Answer 1

You have set the property two times as below :-
System.setProperty("webdriver.firefox.marionette", Path_GecoDriver+"/geckodriver.exe");
System.setProperty("webdriver.gecko.driver", Path_GecoDriver+"/geckodriver.exe");
Remove :-
System.setProperty("webdriver.firefox.marionette", Path_GecoDriver+"/geckodriver.exe");
Another thing is you have to set it before creating the firefox instance. You have define the instance first and then you are setting up the preference .
Try something like below :-
WebDriver driver =null;
public void setup() {
String Path_GecoDriver="C:/Personal/Selenium/setup/geckodriver-v0.18.0-win64";
System.setProperty("webdriver.gecko.driver", Path_GecoDriver+"/geckodriver.exe");
driver= new FirefoxDriver();
}
Hope it will help you :)
