Chromedriver is not downloading the pdf file on clicking the link

Using ChromeDriver version 80.0.3987.106 and the Chrome Capabilities Below.
I want to download a PDF to my local default Downloads location so that the test code can read it for assertions. However, the file is opening in a new Tab in the browser.
public DesiredCapabilities getDesiredCapabilities(Proxy proxySettings) {
TestContext.get().setBrowser("Chrome", "latest");
ChromeOptions options = new ChromeOptions();
HashMap<String, Object> chromePrefs = new HashMap<String, Object>();
chromePrefs.put("profile.default_content_settings.popups", 0);
chromePrefs.put("safebrowsing.enabled", "true");
chromePrefs.put("download.default_directory","C:\\Users\\varghesevineeth\\Desktop\\Vineeth" );
chromePrefs.put("profile.default_content_setting_values.notifications", 2);
chromePrefs.put("plugins.plugins_disabled", new String[] { "Adobe Flash Player", "Chrome PDF Viewer" });
chromePrefs.put("plugins.always_open_pdf_externally", true);
chromePrefs.put("pdfjs.disabled", true);
chromePrefs.put("profile.default_content_setting_values.automatic_downloads", 1);
options.setExperimentalOption("prefs", chromePrefs);
options.addArguments("test-type");
options.addArguments("--ignore-certifcate-errors");
options.addArguments("--disable-extensions");
options.addArguments("start-maximized", "disable-popup-blocking");
options.addArguments("disable-infobars");
options.addArguments("--disable-application-cache");
DesiredCapabilities chromeCapabilities = DesiredCapabilities.chrome();
chromeCapabilities.setCapability("name", MDC.get("testname"));
chromeCapabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
chromeCapabilities.setCapability(ChromeOptions.CAPABILITY, options);
chromeCapabilities.setCapability("download.prompt_for_download", false);
return addProxySettings(chromeCapabilities, proxySettings);

How to download an excel spreadsheet without opening a windows popup window

There is a spreadsheet to download using java+selenium in headless mode.
The thing is I'm using to execute this test cases a Linux server(CI/CD). The code is working 100% correct, When I'm using my local computer(Windows) to execute this code.
ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--disable-infobars");
chromeOptions.addArguments("--browser.helperApps.neverAsk.saveToDisk",
"application/vnd.ms-excel,
vnd.openxmlformats-officedocument.spreadsheetml.sheet,application/excel");
chromeOptions.addArguments("--test-type");
chromeOptions.addArguments("--disable-extensions");
chromeOptions.addArguments("--disable-gpu");
chromeOptions.addArguments("--no-sandbox");
chromeOptions.addArguments("--no-zygote");
chromeOptions.addArguments("--disable-dev-shm-usage");
Map<String, Object> chromePrefs = new HashMap<>();
chromePrefs.put("profile.default_content_settings.popups", 0);
chromePrefs.put("download.prompt_for_download", "false");
chromePrefs.put("cmd", "Page.setDownloadBehavior");
if (OS.startsWith("windows")) {
chromePrefs.put("download.default_directory", path+WIN_RESOURCES_PATH);
System.setProperty("webdriver.chrome.driver", ".\\src\\main\\resources\\driver\\chromedriver.exe");
if (Parameters.instance().getHeadless().toLowerCase().equals("true")) {
chromeOptions.addArguments("--headless");
}
} else if (OS.startsWith("linux")) {
chromePrefs.put("download.default_directory", path+LIN_RESOURCES_PATH);
System.setProperty("webdriver.chrome.driver", Parameters.instance().getChromeDriver());
if (Parameters.instance().getHeadless().toLowerCase().equals("true")) {
chromeOptions.addArguments("--headless");
}
}
chromeOptions.setExperimentalOption("prefs", chromePrefs);
chromeOptions.addArguments("window-size=1920,1080");
driver = new ChromeDriver(chromeOptions);
driver.get(getUrl());
driver.findElement(locator).click;
driver.switchTo().alert().accept();
My code is something like this. When Selenium test clicks the download button, opening another tab in browser and also a popup window, asking where to "Save" the file.
"I'm running these tests in headless chrome"

For me the following code works for pdf download (Windows)
With these option no promot and it will download your predefined path.
System.setProperty("webdriver.chrome.driver", "chromedriver.exe");
Path download_folder = Paths.get(System.getProperty("user.home") + "/Downloads", new String[0]);
HashMap<String, Object> prefs = new HashMap();
prefs.put("download.default_directory", download_folder.toAbsolutePath());
prefs.put("download.prompt_for_download", Boolean.valueOf(false));
prefs.put("download.directory_upgrade", Boolean.valueOf(true));
prefs.put("plugins.plugins_disabled", new String[] { "Chrome PDF Viewer" });
HashMap<String, Object> options = new HashMap();
options.put("prefs", prefs);
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability("chromeOptions", options);
driver = new ChromeDriver(capabilities);

WebDriver save problems in headless mode

I'm using Java+ChromeDriver on Mac for my project.
Here is some code:
System.setProperty("webdriver.chrome.driver", TestConfig.driverURL());
ChromeOptions options = new ChromeOptions();
options.addArguments("headless").addArguments("window-size=2560x1440");
String downloadFilePath = "some file path";
HashMap<String, Object> chromePrefs = new HashMap<String, Object>();
chromePrefs.put("download.default_directory", downloadFilePath);
options.setExperimentalOption("prefs", chromePrefs);
driver = new ChromeDriver(options);
driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
When I comment this line:
options.addArguments("headless").addArguments("window-size=2560x1440");
all is working fine and I download a couple of files, but Chrome doesn't work in headless mode.
When this line is not commented files don't download.
Can anybody tell my how I can download files using ChromeDriwer in headless mode?
Thanks.

Here is what worked for me:
options = Options()
options.add_argument('--headless')
options.add_argument('--disable-gpu')
prefs = {'download.default_directory' : out_path}
options.add_experimental_option('prefs', prefs)
download_path = './output/'
driver = webdriver.Chrome('./chromedriver', chrome_options=options)
driver.command_executor._commands["send_command"] = ("POST",
'/session/$sessionId/chromium/send_command')
params = {'cmd': 'Page.setDownloadBehavior', 'params': {'behavior': 'allow',
'downloadPath': download_path}}
command_result = driver.execute("send_command", params)

Java. Selenium. Chromedriver. How can I enable and disable extensions?

I'm using this code to add own extension, but before load the page it automaticly disabels. How can I enable it?
ChromeOptions options = new ChromeOptions();
options.addArguments("load-extension=...");
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
ChromeDriver driver = new ChromeDriver(capabilities);

To add an extension and disable the plugins with Chrome:
ChromeOptions options = new ChromeOptions();
Map<String, Object> preferences = new Hashtable<String, Object>();
options.setExperimentalOption("prefs", preferences);
// add an extension
options.addExtensions(new File("C:\\extension.crx"));
// disable flash and the PDF viewer
preferences.put("plugins.plugins_disabled", new String[]{
"Adobe Flash Player", "Chrome PDF Viewer"});
ChromeDriver driver = new ChromeDriver(options);
driver.get("https://www.google.co.uk");
