线程“main”中的异常java.lang.NoClassDefFoundError：org / openqa / selenium / WebDriver [英] Exception in thread "main" java.lang.NoClassDefFoundError: org/openqa/selenium/WebDriver

问题描述

我在我的pom.xml中添加了最新的Selenium依赖项

I have added the most updated Selenium dependency in my pom.xml

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>3.7.1</version>
</dependency>

我在我的pom.xml目录中运行
mvn clean install
我还根据Selenium文档在我的app类中导入了正确的类

I ran mvn clean install inside the directory with my pom.xml and I have also imported the correct classes in my app class as per the Selenium documentation

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

然而，当我尝试运行我的main方法时，我收到以下错误

However when i try and run my main method, I get the following error

Exception in thread "main" java.lang.NoClassDefFoundError: 
org/openqa/selenium/WebDriver

我查看〜/ .m2 / repository文件夹，我没有看到openqa文件夹，而是看到seleniumhq文件夹。

I look in my ~/.m2/repository folder and I don't see an openqa folder but instead I see a seleniumhq folder.

为什么没有maven安装openqa文件夹，为什么文档说要从org.openqa导入...当我的jar存储库中从不存在。我很困惑，我只是希望能够在我的本地存储库中成功导入selenium Webdriver。

Why didn't maven install the openqa folder, and why does the documentation say to import from org.openqa... when that never exist in my jar repository. I'm very confused, I just want to be able to import selenium Webdriver successfully while having it in my local repository.

推荐答案

我在线程main中遇到过这个异常的经验java.lang.NoClassDefFoundError：org / openqa / selenium / WebDriver 错误并希望分享自己的解决方案：

I had experience with this Exception in thread "main" java.lang.NoClassDefFoundError: org/openqa/selenium/WebDriver error and want to share own solution:

当我收到此错误时，我使用<$在IntelijIDEA中启动了我的应用程序编辑配置中的c $ c> Jar （让我们检查）：

When I get this error, I launched my application in IntelijIDEA using Jar in Edit Configuration (let's check):

错误是：

And the error was:

Exception in thread "main" java.lang.NoClassDefFoundError: org/openqa/selenium/WebDriver
    at project.Main.main(Main.java:45)
Caused by: java.lang.ClassNotFoundException: org.openqa.selenium.WebDriver
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:335)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    ... 1 more

所以，我添加而不是 Jar应用 - > 应用：

此处也发生了变化：

So, I added instead of Jar Application -> Application: And here changed too:

它帮助我解决了错误。

注意：我的依赖关系就像

        <dependency>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-java</artifactId>
            <version>2.53.1</version>
        </dependency>
