Selenium 3.7 : geckodriver : WebDriverException: org.apache.http.conn.HttpHostConnectException Connection Refused

Recently I upgraded to Selenium 3.7.

Code:

import org.openqa.selenium.WebDriver;  
import org.openqa.selenium.firefox.FirefoxDriver;


public static void main (String args[]){

    System.setProperty("webdriver.gecko.driver", 
    "/usr/local/bin/geckodriver");      
    WebDriver driver = new FirefoxDriver();
    driver.get("http://www.google.com");
    driver.quit();
  }

Included Library:

Error trace log:

Any idea would be appreciated. Thank you.

Update after trying Debanjan suggestion:

Code:

public static void main (String args[]){
    System.out.println("Debug 1");
    System.setProperty("webdriver.gecko.driver", 
    "/Users/maggie/Documents/ToolsQA/Libs/geckodriver");    
    System.out.println("Debug 2");
    WebDriver driver = new FirefoxDriver();
    System.out.println("Debug 3");
    driver.get("http://www.google.com");
    driver.quit();
  }

The error WebDriverException: org.apache.http.conn.HttpHostConnectException: Connect to localhost:8970 can occur due to different reasons. More over there is a discrepency in your Included Library list as selenium-server-standalone-3.7.1.jar is never a part of downloaded selenium-java-3.7.1.zip.

Try out the steps mentioned below:

From the Included Library list remove all the jars.
Download and Add only selenium-server-standalone-3.7.1.jar from this link or from this link
Ensure that /etc/hosts on your system contains the following entry :
```
1 127.0.0.1               localhost.localdomain localhost
```
Run CCleaner Tool to wipe away all the OS chores from your system.
You can opt for a System Reboot.
Execute your Test.

I tried with the same versions without any problem.

If the path to the geckodriver:

System.setProperty("webdriver.gecko.driver", 
    "/usr/local/bin/geckodriver");

is correct, make sure that the geckodriver is executable for the user that execute the code:

chmod +x geckodriver

After doing some research, I manage to resolve this problem.

The error is due to the 127.0.0.1 map to localhost.com in etc/hosts. Edited: 127.0.0.1 localhost

I think you are missing the .exe extension. Your path should be like this

System.setProperty("webdriver.gecko.driver", 
    "/usr/local/bin/geckodriver.exe");
