Having issue building TestG maven project in Jenkins

Question

I have an issue with building TestNG based Maven project via Jenkins. The issue is that if I have less number of test to run (up to 30) everything runs fine, but as soon as I increase the number, the build fails consistently. The problem I see is that, tests doesn't start until all the browser instance are open (eg, browser opens 30 windows first then start execution for suite of 30 tests) and when the test gets complete(not entire test suite), the browser window doesn't close (even after adding driver.quit() method) and it remains open till the TestSuite run is complete.

Below is snippet of my code.

Main Java class: 

public class AccountManagement {
    public WebDriver driver = new FirefoxDriver();
    public WebDriverWait wait = new WebDriverWait(driver, 20);
    public void login(String uid, String pass) throws Throwable {
        driver.manage().window().maximize();
        driver.get(URL);
        driver.findElement(By.id("Email")).sendKeys(uid);
        driver.findElement(By.id("Password")).sendKeys(pass);
        driver.findElement(By.id("btnLogin")).click();

        <!-- REST OF THE CODE-->
    }
}

Sample test class: 

public class TC_AC408 extends AccountManagement {

    @Test(retryAnalyzer=Retry.class)
    public void accountActionLinks() {
        login("auto.admin@test.com", "test@123");
        <!-- REST OF THE CODE-->
    }

    @AfterTest
    public void end() {
        driver.quit();
    }
}

Here is my testng.xml:

You are creating driver instance whenever for every class inside a test and quitting driver only once per test.Instead of instantiating WebDriver directly in class do it in @BeforeTest. It will ensure only one driver is created per test.

Your class whould look like below after upation. 

public class AccountManagement {
public WebDriver driver;
public WebDriverWait wait;
@BeforeTest
public void beforeTest(){
    driver = new FirefoxDriver();
    wait = new WebDriverWait(driver, 20);
}
public void login(String uid, String pass) throws Throwable {
    driver.manage().window().maximize();
    driver.get(URL);
    driver.findElement(By.id("Email")).sendKeys(uid);
    driver.findElement(By.id("Password")).sendKeys(pass);
    driver.findElement(By.id("btnLogin")).click();

    <!-- REST OF THE CODE-->
 }
}
