php小编新一带来的Java问答:在开发JavaFX应用程序时,有时会遇到异常java.lang.NoClassDefFoundError,错误提示为org/openqa/selenium/WebDriver。这个异常通常表示缺少WebDriver类的依赖包,需要在项目中添加相应的依赖以解决该问题。接下来我们将详细介绍如何处理这种异常,并提供解决方案,让您顺利解决线程问题。

问题内容

根据我当前的代码,有什么可能导致此异常的线索吗?

运行以下代码时:

main.java

package application; import java.io.ioexception; import javafx.application.application; import javafx.stage.stage; import javafx.scene.scene; import javafx.scene.control.button; import javafx.scene.layout.gridpane; public class main extends application { @override public void start(stage primarystage) throws ioexception { button runbutton = new button("run"); runbutton.setonaction(e -> { test test = new test(); }); gridpane gridbox = new gridpane(); gridbox.add(runbutton, 0, 0); scene scene = new scene(gridbox, 380, 150); primarystage.setscene(scene); primarystage.show(); } public static void main(string[] args) { launch(args); } }

测试.java

package application; import org.openqa.selenium.webdriver; import org.openqa.selenium.chrome.chromedriver; public class test { webdriver driver; public static void main(string[] args) { test obj = new test(); obj.setupwebsite(); } public void setupwebsite() { //creates chrome window. driver = new chromedriver(); //sets up window to maximize and go to brink website. driver.manage().window().maximize(); driver.get("https://www.google.com"); } }

我得到的只是以下内容:

我已确认我的所有 jar 文件都位于正确的位置。我可以单独运行 test.java 文件。我有这个代码的更大版本,最初认为这是由于整个代码有问题,但发现即使精简到这个,它仍然会继续。

解决方法

想通了。我必须将所有 JAR 文件添加到运行配置类路径中。
