Getting initialization error "NoClassDefFoundError: cucumber/runtime/io/URLOutputStream" after integrating cucumber.adapter.ExtentCucumberAdapter

Question

黄瓜 V.4.2.3 |硒 V.3.8.1 | JUnit V.4.12 |范围报告 V.3.1.1

我在 RunCuke Java 文件 Java 文件

中集成 "com.aventstack.extentreports.cucumber.adapter.ExtentCucumberAdapter:" 时遇到错误 "java.lang.NoClassDefFoundError: cucumber/runtime/io/URLOutputStream"

package com.jacksparrow.automation.suite.runner;

import org.junit.runner.RunWith;
import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;

@RunWith(Cucumber.class)
@CucumberOptions(features = "classpath:features/functional/",
                     glue = {"com.jacksparrow.automation.steps_definitions.functional" },
                     tags = { "@guest_plp" },
                   plugin = { "pretty","json:target/cucumber-json/cucumber.json",
                              "junit:target/cucumber-reports/Cucumber.xml", "html:target/cucumber-reports",
                              "com.aventstack.extentreports.cucumber.adapter.ExtentCucumberAdapter:"},
                   strict = false,
                   dryRun = false,
               monochrome = true)

public class FunctionalRunCuke {
}

Error Screen Shot from Eclipse

尝试在 POM.xml 中添加扩展黄瓜适配器，如下所示 -

    <dependency>
            <groupId>com.aventstack</groupId>
            <artifactId>extentreports-cucumber4-adapter</artifactId>
            <version>1.0.5</version>
        </dependency>

        <dependency>
            <groupId>com.aventstack</groupId>
            <artifactId>extentreports</artifactId>
            <version>3.1.1</version>
        </dependency>

        <dependency>
            <groupId>com.vimalselvam</groupId>
            <artifactId>cucumber-extentsreport</artifactId>
            <version>3.1.1</version>
        </dependency>

如果我删除 "extentreports-cucumber4-adapter" 那么我不会得到下面提到的编译时错误 -

我在POM.xml

以前有人遇到过这个问题。 Cucumber V 4.2.3 是否支持 extentreports-cucumber4-adapter 插件。如果是这样，那么任何猜测，这里有什么问题导致了这个错误。

Answer 1

出现此问题是因为您将 ExtentReports 版本 3 与 cucumber 适配器一起使用，这仅适用于版本 ExtentReports v4。如果删除依赖项不能解决问题，我建议分享您的 pom.xml.

Answer 2

解决方案已经由@Grasshopper 提供，但在评论部分。所以，我想我会把它放在主要部分，因为有些用户可能不会浏览所有评论。

如果我们使用 cucumber-java 版本 > v4.2.0，就会出现此错误。所以，如果您使用的是最新版本，请将其降级到 v4.2.0。

为了您的理解，这是我的 pom 的样子：

    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-java</artifactId>
        <version>4.2.0</version>
    </dependency>

    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-core</artifactId>
        <version>4.2.0</version>
    </dependency>

    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-junit</artifactId>
        <version>4.2.0</version>
    </dependency>

Answer 3

以上问题将通过添加以下依赖得到解决

<!-- https://mvnrepository.com/artifact/com.aventstack/extentreports-cucumber4-adapter -->
    <dependency>
        <groupId>com.aventstack</groupId>
        <artifactId>extentreports-cucumber4-adapter</artifactId>
        <version>1.0.8</version>
    </dependency>
