Couldn't load plugin class: com.qmetry.qaf.automation.cucumber.QAFCucumberPlugin. It does not implement cucumber.api.Plugin

Question

I planning to use qaf-cucumber library for scenario outlines testdata with external files.

Repo: https://github.com/qmetry/qaf-cucumber Branch: cucumber-4

When I run my runner class I'm getting below error: Couldn't load plugin class: com.qmetry.qaf.automation.cucumber.QAFCucumberPlugin. It does not implement cucumber.api.Plugin

For cucumber-4 support you need to use qaf-cucumber4 dependency instead of qaf-cucumber.

I am able to find everything working with following setup:

POM:

    <dependencies>
        <dependency>
            <groupId>com.qmetry</groupId>
            <artifactId>qaf</artifactId>
            <version>2.1.15</version>
        </dependency>
        <dependency>
            <groupId>com.qmetry</groupId>
            <artifactId>qaf-cucumber4</artifactId>
            <version>2.1.15</version>
        </dependency>
        <dependency>
            <groupId>io.cucumber</groupId>
            <artifactId>cucumber-java</artifactId>
            <version>4.8.0</version>
        </dependency>
        <dependency>
            <groupId>io.cucumber</groupId>
            <artifactId>cucumber-junit</artifactId>
            <version>4.8.0</version>
            <scope>test</scope>
        </dependency>
    </dependencies>

Runner:

package com.example;
import io.cucumber.junit.CucumberOptions;
import io.cucumber.junit.Cucumber;
import org.junit.runner.RunWith;
@RunWith(Cucumber.class)
@CucumberOptions(
    features="Features",
    glue={"com.example.common"},
    monochrome=true,
    plugin = {"com.qmetry.qaf.automation.cucumber.QAFCucumberPlugin","pretty"}
)

public class JunitRunner {

}

Feature file:

Feature: Test cucumber  
  
   @smoke
  Scenario: Search Keyword
  Given I am on Google Search Page
  When I search for "qaf"
  
  @smoke
  @datafile:resources/testdata.json
  Scenario Outline: Search Keyword using data from file
  Given I am on Google Search Page
  When I search for "<searchKey>"

data file:

[
    {
        "searchKey": "qaf selenium"
    },
    {
        "searchKey": "selenium ecosystem frameworks"
    }
]
