When runing cucumber from main method giving me skeleton of my features

Question

When running the cucumber test runner from main class as per below screenshot just giving me the skeleton of the feature to define the steps. Whereas I have already written the code to achieve the steps.

Attaching screenshot to understand my code as well project structure. Mainjarvish.java is the main file from where I am trying to run the TestRunner.java.

It fails because your class test/java/stepDefinitions/Contacts is not in the same class path scope as src/main/java/MainJarvish.

Assume following structure.

src/main/java/MainJarvish.java
src/test/java/stepDefinitions/Contacts.java
src/test/java/FeatureList/Smoke.feature

MainJarvish.java

import cucumber.api.cli.Main;

public class MainJarvish {
    public static void main(String[] args) throws Exception {
        String[] options = {"--glue", "stepDefinitions",
            "src/test/java/FeatureList/Smoke.feature"};
        byte exitcode = Main.run(options, Thread.currentThread().getContextClassLoader());
        System.out.println("exitcode = " + exitcode);
    }
}

Contacts.java

package stepDefinitions;

import cucumber.api.java.en.Given;

public class Contacts {
    @Given("^Submit message for execution$")
    public void submitMessageForExecution() throws Throwable {
        System.out.println("submitMessageForExecution");
    }
}

Smoke.feature

Feature: example feature

  Scenario: describe the test scenario
    Given Submit message for execution

compile the classes

mvn clean compile test-compile

it generates the class files

target/classes/MainJarvish.class
target/test-classes/stepDefinitions/Contacts.class

When you now execute ManJarvish

mvn exec:java -Dexec.mainClass=MainJarvish

the class Contacts is not on the class path and therefor the step definition is not found.

[INFO] --- exec-maven-plugin:1.6.0:java (default-cli)
...
Undefined scenarios:
src/test/java/FeatureList/Smoke.feature:3 # describe the test scenario

1 Scenarios (1 undefined)
1 Steps (1 undefined)

As MainJarvish is located in src/java at its execution only the project classes below target/classes are added to the class path.

If the class Contacts would be on the class path, e.g. by changing the class path scope

mvn exec:java -Dexec.mainClass=MainJarvish -Dexec.classpathScope="test"

now are the classes below target/classes and below target/test-classes added to the class path and the step definition is found.

[INFO] --- exec-maven-plugin:1.6.0:java (default-cli)
submitMessageForExecution

Depending on what you want to achieve you might consider to move MainJarvish to test/java or create a test runner class.

src/test/java/TestRunner.java

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

@RunWith(Cucumber.class)
@CucumberOptions(
        glue = "stepDefinitions",
        features="src/test/java/FeatureList/Smoke.feature"
)
public class TestRunner {
}

then you can run your feature test as

mvn clean test

output
