Answer 1

했다 동일한 문제입니다. 시스템에서 이전 Java JDK를 제거하고 Java8로 빌드하도록 설정했으며 마술처럼 작동했습니다.

Answer 2

웹 사이트를 연 후에 "액세스 거부"오류가 발생합니다. 아래 코드가 작동하는 경우에도 계속 시도하십시오. -

import org.openqa.selenium.By; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.WebElement; 
import org.openqa.selenium.chrome.ChromeDriver; 
import org.openqa.selenium.chrome.ChromeDriverService; 
import org.openqa.selenium.chrome.ChromeOptions; 

import java.io.IOException; 

public class test { 
    @SuppressWarnings("null") 
    public static void main(String[] args) { 

     String Browser_Full_path = Driver.APP_PATH + "\\Support JAR\\32 bit\\BrowserDrivers\\" + "chromedriver.exe"; 
     System.out.println(" browser full path => " + Browser_Full_path); 
     System.setProperty("webdriver.chrome.driver", Browser_Full_path); 
     ChromeDriverService cds = ChromeDriverService.createDefaultService(); 
     try { 
      cds.start(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 

     ChromeOptions options = new ChromeOptions(); 
     options.addArguments("--start-maximized"); 
     WebDriver driver = new ChromeDriver(options); 

     driver.get("http://www.cvs.com"); 
     WebElement signuplink = null; 
     signuplink.findElement(By.partialLinkText("signup")); 
     WebElement Clicklink = null; 
     Clicklink.click(); 
    } 
}
