Question

I am trying to obtain a report in my maven project using Cucumber, and ExtentReport. I am using java 8. Here are my dependencies:
<dependencies>
<!-- https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-java -->
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-java</artifactId>
<version>3.4.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/info.cukes/cucumber-java -->
<dependency>
<groupId>info.cukes</groupId>
<artifactId>cucumber-java</artifactId>
<version>1.2.5</version>
</dependency>
<!-- https://mvnrepository.com/artifact/info.cukes/cucumber-junit -->
<dependency>
<groupId>info.cukes</groupId>
<artifactId>cucumber-junit</artifactId>
<version>1.2.5</version>
<scope>test</scope>
</dependency>
<!-- https://mvnrepository.com/artifact/com.vimalselvam/cucumber-extentsreport -->
<dependency>
<groupId>com.vimalselvam</groupId>
<artifactId>cucumber-extentsreport</artifactId>
<version>3.1.1</version>
</dependency>
</dependencies>
and then i used the below runner class, to run all my *.feature files:
import org.junit.runner.RunWith;
import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;
#RunWith(Cucumber.class)
#CucumberOptions(
features = {"src/test/resources/features" },
monochrome = true,
plugin = {"com.vimalselvam.cucumber.listener.ExtentCucumberFormatter:output/report.html"},
glue = {"stepDefinitions"}
)
public class TestRunnerJUnit {
}
But when i run the test-Runner, it complains with:
cucumber.runtime.CucumberException: java.lang.NoClassDefFoundError: com/aventstack/extentreports/reporter/ExtentHtmlReporter

Update:
When i add the below dependency:
<dependency>
<groupId>com.aventstack</groupId>
<artifactId>extentreports</artifactId>
<version>3.1.1</version>
</dependency>
I receive this new error:

Answer 1

try to replace this
<dependency>
<groupId>com.aventstack</groupId>
<artifactId>extentreports</artifactId>
<version>3.1.1</version>
</dependency>
with this one
<dependency>
<groupId>com.aventstack</groupId>
<artifactId>extentreports</artifactId>
<version>3.0.7</version>
</dependency>
the component "cucumber-extentsreport" and "extentreports" are different things.
I had the same issue and solved by using "extentreports" version 3.0.7 with "cucumber-extentsreport" version 3.1.1
Good luck!

Answer 2

I got the answer.
Everything was fine, but i needed to added a value to Feature in the *.feature file.
So, here you can see the Feature key word should exist, and exactly in front of it should be a text. If you write the text in next line, you will face with the error.
Feature: Check Welcome-message
As a user, I should find a welcome-message in my mailbox, and my age in my profile.
