java.lang.Error:未解决的编译问题:WebDriver/ChromeDriver 在执行 selenium

问题描述

这是我的代码:

package seleniumTutorials;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;

public class BasicsSelenium {

public static void main(String[] args) {
    boolean status;
    status=true;
    boolean newstatus = false;

    System.out.println("My Old status was "+status);
    System.out.println("My new status was "+newstatus);
    System.setProperty("webdriver.chrome.driver", "F:\Samraj\MavenAutomation\Jar Files\Selenium Java\chromedriver.exe");
    ChromeOptions chromeOptions = new ChromeOptions();
    chromeOptions.addArguments("--start-maximized");
    WebDriver driver = new ChromeDriver(chromeOptions);
    driver.get("dev.findmyfare.io");
    System.out.println(driver.getTitle());
 }
 }

以下是声明 webdriver 概念后得到的错误消息:

Below is the error message which am getting after declaring webdriver concept:

Exception in thread "main" java.lang.Error: Unresolved compilation problems: 
WebDriver cannot be resolved to a type   ChromeDriver cannot be resolved to a type
    at seleniumTutorials.BasicsSelenium.main(BasicsSelenium.java:13)

注意:我可以执行简单的java程序.

Note: I can able to execute simple java program.

推荐答案

这个错误信息...

Exception in thread "main" java.lang.Error: Unresolved compilation problems:
WebDriver cannot be resolved to a type
ChromeDriver cannot be resolved to a type

...暗示 WebDriver 和 ChromeDriver 在编译时没有解决.

...implies that WebDriver and ChromeDriver wasn't resolved at compiletime.

根据您分享的快照，您的主要问题是您的项目空间中存在多个类似的二进制文件，如下所示:

As per the snapshot you have shared your main issue is the presence of multiple similar binaries within your project space as follows :

• 您已将 selenium-server-standalone-3.11.0 作为依赖项.
• 此外，您还包含了来自 selenium-java-3.11.0 的 Java 客户端 JAR 作为依赖项.

• You have included selenium-server-standalone-3.11.0 as a dependency.
• Additionally you have included the Java Client JARs from selenium-java-3.11.0 as a dependency.

因此，您很可能已经从一个 JAR 资源(即 selenium-server-standalone-3.11.0 或 selenium-java-3.11.0 JAR)，但 compiletime 类正试图从其他 JAR 中解析.因此您会看到 java.lang.Error: Unresolved compiler questions

As a result it is pretty much possible that you have resolved the WebDriver and ChromeDriver from one JAR resource (i.e. either selenium-server-standalone-3.11.0 or selenium-java-3.11.0 JARs) but compiletime the Classes are trying to get resolved from the other JAR. Hence you see java.lang.Error: Unresolved compilation problems

• 要么只保留 selenium-server-standalone-3.11.0 JAR 作为外部 JAR.
• 或者只保留 selenium-java-3.11.0 JAR 作为外部 JAR.
• 删除所有其他 Selenium Java 客户端 JAR.
• 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.
• 进行一次系统重启.
• 执行你的 @Test.

• Either keep only selenium-server-standalone-3.11.0 JAR as an external JAR.
• Or keep only selenium-java-3.11.0 JARs as an external JARs.
• Remove all the other Selenium Java Client JARs.
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• Take a System Reboot.
• Execute your @Test.
