java.lang.NoClassDefFoundError：net.jodah.failsafe.Policy

Question

对于自动化以及与 Java 相关的所有事物，我都是新手。

从 IntelliJ 执行用 Java 编写的自动化代码时，我遇到了下面给出的错误：

我的部分代码：

public final class AssertionsExample2 {

    WebDriver driver;

    @BeforeClass
    void setup()
    {
        System.setProperty("webdriver.chrome.driver", "C:/Users/tlwri/IdeaProjects/sampleJavaProject/Drivers/chromedriver_win32/chromedriver.exe");
        driver=new ChromeDriver();
    }
    @Test (priority = 1)
    void logoTest()
    {
        WebElement logo=driver.findElement(By.xpath("//*[@id=\"divLogo\"]/img"));
        Assert.assertTrue(logo.isDisplayed(),"Logo is not displayed on the page");
    }

如何修复这个错误？

Answer 1

我在 Intellij IDEA 中运行 Selenium 时遇到类似的错误。 除了 thMe odule 设置菜单下的“selenium-java-[version]”文件夹之外，我还通过将“selenium-java-[version]/lib”添加到全局库来修复此问题。

Answer 2

我遇到了同样的问题，通过下载failsafe .jar（https://mavenlibs.com/jar/file/dev.failsafe/failsafe）并将其添加到类路径

解决了这个问题

Answer 3

我遇到了这个错误，当我添加 selenium lib 文件夹中的所有 jar 时，它消失了。

Answer 4

您的

Maven

/Gradle 项目中缺少 failsafe 依赖项/库：

Maven（pom.xml）：

<dependency>
    <groupId>net.jodah</groupId>
    <artifactId>failsafe</artifactId>
    <version>2.4.4</version>
</dependency> 

Gradle（构建.gradle）：

dependencies {
  implementation group: 'net.jodah', name: 'failsafe', version: '2.4.4'
}
