问题描述

我开发的 selenium 代码:​​

I develop the selenium code that:

    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.edge.EdgeDriver;
    import org.openqa.selenium.firefox.FirefoxDriver;
    import org.openqa.selenium.support.ui.Select;
    import java.util.List;

    public class TestDemoQA {
        public static void main(String[] args) throws InterruptedException{
            System.setProperty("webdriver.edge.driver", "C:\Users\Suganthan\Downloads\MicrosoftWebDriver.exe");
            WebDriver driver = new EdgeDriver();
            driver.get("http://demoqa.com/");
            driver.manage().window().maximize();`

我收到的错误是:

Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkState(ZLjava/lang/String;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)

我正在尝试根据 此解决方案通过升级 guava 来解决此问题-21.0.但我仍然收到此错误.谁能给出解决方案?

I'm trying to solve this issue according to This Solution by upgrading guava-21.0. But I'm still getting this error. could anyone give a solution to solve it?

推荐答案

这个错误信息...

Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkState(ZLjava/lang/String;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)

...暗示 JVM 无法启动/生成您的程序.

...implies that the JVM was unable to initiate/spawn your program.

正如@GhostCat 指出的那样,您的主要问题是 guava 版本与您正在使用的其他二进制版本之间的不兼容.

As @GhostCat pointed your main issue is the incompatibility between the guava version and other binary versions you are using.

  • JDK 升级到最新级别 <强>JDK 8u181.
  • Selenium 升级到当前级别版本 3.14.0.
  • 当您删除以前版本的 Selenium Client 时,请确保正确删除所有关联的 jars.
  • 清理你的项目工作区通过你的IDE重建你的项目只需要依赖.
  • 执行你的 @Test.
  • Upgrade JDK to recent levels JDK 8u181.
  • Upgrade Selenium to current levels Version 3.14.0.
  • When you remove the previous version of Selenium Client ensure that all the associated jars are properly removed.
  • Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
  • Execute your @Test.
