How to address “The constructor ChromeDriver(Capabilities) is deprecated” and WebDriverException: Timed out error with ChromeDriver and Chrome

问题

I'm trying to config the default download directory as below, it's works correctly but I'm having two issues :

    String exePath = "src\\Drivers\\chromedriver.exe";
    System.setProperty("webdriver.chrome.driver", exePath);
    String downloadFilepath = "U:\\Data\\Download";
    HashMap<String, Object> chromePrefs = new HashMap<String, Object>();
    chromePrefs.put("profile.default_content_settings.popups", 0);
    chromePrefs.put("download.default_directory", downloadFilepath);
    ChromeOptions options = new ChromeOptions();
    options.setExperimentalOption("prefs", chromePrefs);
    DesiredCapabilities cap = DesiredCapabilities.chrome();
    cap.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
    cap.setCapability(ChromeOptions.CAPABILITY, options);
    driver = new ChromeDriver(cap);
    driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);

1. It's telling me that The constructor ChromeDriver(Capabilities) is deprecated

2. When I replay the test several times it happens to have a Webdrive TimeOut exception

It seems you were almost there. You need to use the method merge() from MutableCapabilities Class to merge the DesiredCapabilities type of object into ChromeOptions type object and initiate the WebDriver and WebClient instance by passing the ChromeOptions object as follows :

String exePath = "src\\Drivers\\chromedriver.exe";
System.setProperty("webdriver.chrome.driver", exePath);
String downloadFilepath = "U:\\Data\\Download";
HashMap<String, Object> chromePrefs = new HashMap<String, Object>();
chromePrefs.put("profile.default_content_settings.popups", 0);
chromePrefs.put("download.default_directory", downloadFilepath);
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("prefs", chromePrefs);
DesiredCapabilities cap = DesiredCapabilities.chrome();
cap.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
cap.setCapability(ChromeOptions.CAPABILITY, options);
options.merge(cap);
driver = new ChromeDriver(options);
