A fresh installation of eclipse has been created as a result of this error (I deleted all the files, however I'm guessing I missed a few)
This is the error:

Getting it on a brand new project too so believe this is away from any project specific configuration.
Can anyone assist?

As per your code, you are not initializing your driver variable. The basic code would be -
WebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com");
Also, based on what browser you want to use, you would need to download and then setup the corresponding driver as well. For Firefox, it's called GeckoDriver and for Chrome it's called ChromeDriver. Finally, you would need to provide the driver location in your script. So the code would look like this -
System.setProperty("webdriver.gecko.driver", "C:\\some_folder\\geckodriver.exe");
FirefoxDriver driver = new FirefoxDriver();
driver.get("http://www.google.com");
If you are looking for detailed steps, then you can follow this article - Selenium WebDriver Setup
In your code it seems that you haven't initialized your driver
So you might want to add two statements before you write driver.get(); statement.
System.setProperty("webdriver.chrome.driver",System.getProperty("user.dir")+"\\lib\\chromedriver.exe");
//Or any other browser's driver that you have used.
driver = new ChromeDriver();

I would recommend using the Gradle Test Runner so that you don't have to set the javaagent flag manually.
To use Gradle Test Runner Click the Run/Debug configuration drop down > Edit Configurations... > + > Gradle In the form that appears, fill in the details:

private WebElement buttonSignIn in the DefaultPage class does not appear to ever be instantiated. Your regex might be failing
I was trying to edit my code - when i input row with xpath into my test it works perfectly. When I trying to copy same Xpath into DefaultPage class error message is displayed. Have no idea why.
public void incorrectEmailLoginPage() {
driver.findElement(By.xpath("//*[#id='header']/div[2]/div/div/nav/div[1]/a")).click();

In your AccountTest class you are declaring WebDrive driver; again which setting to driver=null, this cause HomePage driver to be null; Also you do not need getter for webDriver. This should work just fine
public class AccountTest extends TestBase {
#Test
public void shouldLogIn() {
HomePage onHomePage = PageFactory.initElements(driver, HomePage.class);
System.out.println("Step 1 ");
MyAccount onMyAccount = onHomePage.clickOnMyAccount();
System.out.println("Step 2");
LogInResultPage onResultPage = onMyAccount.LogIn().submitForm();
System.out.println("Step 3");
wait(2000);
Assert.assertTrue(onResultPage.getMessage().contains("ERROR"));
}
public void wait(int seconds){
try {
Thread.sleep(2000);
} catch (final InterruptedException e) {
e.printStackTrace();
}
}
}
I am using pageObject Model for my selenium automation.
Consider following browser config class.
package BrowserConfig;
import org.junit.After;
import org.junit.Before;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
public class crossBrowserConfiguration {
By logInPanel = By.xpath("//div[#id='logInPanelHeading']");
public static WebDriver driver = null;
WebDriverWait wait = new WebDriverWait(driver,30);
#Before
public void initBrowser(){
driver = new FirefoxDriver();
driver.manage().window().maximize();
driver.get("Website that contains Login Page");
wait.until(ExpectedConditions.visibilityOfElementLocated(logInPanel));
}
#After
public void closeBrowser(){
driver.quit();
}
}
I have a page object of Log in screen.
package PageObjects;
import org.openqa.selenium.By;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import BrowserConfig.crossBrowserConfiguration;
public class LoginScreen extends crossBrowserConfiguration {
WebDriverWait wait = new WebDriverWait(driver,30);
By userName = By.xpath("//input[#id='txtUsername']");
By password = By.xpath("//input[#id='txtPassword']");
By loginButton = By.xpath("//input[#id='btnLogin']");
By welcomeNote = By.xpath("//a[#id='welcome']");
By empListVerify = By.xpath("//div[#id='employee-information']/a");
public void logIN(String UserName, String Password){
driver.findElement(userName).sendKeys(UserName);
driver.findElement(password).sendKeys(Password);
driver.findElement(loginButton).click();
wait.until(ExpectedConditions.visibilityOfElementLocated(welcomeNote));
//Employee List Verification
String empListBtnText = driver.findElement(empListVerify).getText();
System.out.println(empListBtnText);
}
}
And finally, I have the following test case script:
package TestCases;
import org.junit.Test;
import BrowserConfig.crossBrowserConfiguration;
import PageObjects.LoginScreen;
public class initiateBrows extends crossBrowserConfiguration{
LoginScreen Obj1 = new LoginScreen();
#Test
public void runThis() throws Exception{
Obj1.logIN("admin", "123456");
}
}
When I run my test as JUnit Test, it gives nullPointerException without running at all. Stack trace for the exception is:

refers to WebDriverWait wait = new WebDriverWait(driver,30);
Any insight into why am I facing this exception?
The wait field is initialized when the an object of the class is created. This happens before JUnit calls the #Before method. Therefore the driver object is null. There are different ways of fixing the issue. One is making the driver object a simple field and initialize it immediately.
public class crossBrowserConfiguration {
By logInPanel = By.xpath("//div[#id='logInPanelHeading']");
public final WebDriver driver = new FirefoxDriver();
WebDriverWait wait = new WebDriverWait(driver,30);
#Before
public void initBrowser(){
driver.manage().window().maximize();
driver.get("Website that contains Login Page");
wait.until(ExpectedConditions.visibilityOfElementLocated(logInPanel));
}
#After
public void closeBrowser(){
driver.quit();
}
}
