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.

将 JDK 升级到最新级别 <强>JDK 8u181.
将 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和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.
