线程“main”java.lang.AbstractMethodError中的Selenium Chrome驱动程序异常：运行测试时接收器类org.openqa.selenium.chrome错误

Question

我刚刚将现有项目转换为 Maven 项目。我添加了依赖项，如 selenium-java、selenium-serve、selenium-chrome-driver、testing 和 JUnit。

它是一个TestNG项目，包含许多包和类。它给了我一个错误，如下所示：

Exception in thread "main" java.lang.AbstractMethodError: Receiver class org.openqa.selenium.chrome.ChromeDriverService$Builder does not define or inherit an implementation of the resolved method 'abstract void loadSystemProperties()' of abstract class org.openqa.selenium.remote.service.DriverService$Builder.
    at org.openqa.selenium.remote.service.DriverService$Builder.build(DriverService.java:504)
    at org.openqa.selenium.chrome.ChromeDriverService.createDefaultService(ChromeDriverService.java:162)
    at org.openqa.selenium.chrome.ChromeDriver.<init>(ChromeDriver.java:52)

我添加的依赖项；

<dependencies>

            <version>1.0.41</version>
        </dependency>


    </dependencies>

我还在我的鳕鱼中添加了这一行，

        System.setProperty("webdriver.chrome.driver", "path");
        WebDriver driver = new ChromeDriver();

谁能帮我解决这个错误。我该怎么办？

Answer 1

这个错误信息...

Exception in thread "main" java.lang.AbstractMethodError: Receiver class org.openqa.selenium.chrome.ChromeDriverService$Builder does not define or inherit an implementation of the resolved method 'abstract void loadSystemProperties()' of abstract class org.openqa.selenium.remote.service.DriverService$Builder

...暗示类没有实现父类的正确方法。

出现这种情况是因为版本/依赖不匹配。

这个用例

在您的

pom.xml

中，同一任务有 2 个不同的依赖项。

• selenium-java：

  https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-java -->
  <dependency>
      <groupId>org.seleniumhq.selenium</groupId>
      <artifactId>selenium-java</artifactId>
        <version>4.10.0</version>
  </dependency>
  

• 硒服务器：

  https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-server -->
  <dependency>
      <groupId>org.seleniumhq.selenium</groupId>
      <artifactId>selenium-server</artifactId>
      <version>3.9.0</version>
  </dependency>

解决方案

删除任何一个依赖项，你就可以开始了。
