Selenium：未知的 HttpClient 工厂 netty

Question

使用 ProcessBuilder (java) 执行 selenium 代码时，收到以下错误消息：

Exception in thread "main" java.lang.ExceptionInInitializerError

硒代码如下：

   import org.openqa.selenium.chrome.ChromeDriver;

public class SeleniumProto {
    public SeleniumProto() {
    }

    public static void main(String[] var0) {
        System.setProperty("webdriver.chrome.driver", "C:\\Users\\OneDrive\\Documents\\chromedriver.exe");
        ChromeDriver var1 = new ChromeDriver();
        var1.get("https://www.twitter.com");
    }
}

网上关于如何解决此问题的答案并不多。

Answer 1

看起来像是与 selenium 版本或错误的 webdriver 版本有关的问题。试试这个：

    public static void main(String[] args) {
        WebDriverManager.chromedriver().setup();
        ChromeDriver driver = new ChromeDriver();
        driver.get("https://www.twitter.com");
    }

使用以下依赖项：

        <!-- https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-java -->
        <dependency>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-java</artifactId>
            <version>4.6.0</version>
        </dependency>

        <!-- https://mvnrepository.com/artifact/io.github.bonigarcia/webdrivermanager -->
        <dependency>
            <groupId>io.github.bonigarcia</groupId>
            <artifactId>webdrivermanager</artifactId>
            <version>5.3.1</version>
        </dependency>

Answer 2

我遇到了相同或类似的问题。我将

selenium-java

依赖项从 4.5 更新到最新的 4.18.1，然后立即出现此错误以及其他运行时错误。这很可能是由于

selenium-java

周围不兼容造成的。 当我将版本撤回到 4.5 时，错误就消失了。
