How to fix cucumber step does not have matching glue code?

Question

The cucumber feature file has all steps highlighted in yellow and warning is shown as step does not have matching glue code, When I try to run the project as maven test, I am getting null pointer exception for all steps.

TestRunner[Feature[Steps

Test Runner class:

package com.vtiger.CucumberFramework.testRunner;

import org.junit.runner.RunWith;

import io.cucumber.junit.Cucumber;
import io.cucumber.junit.CucumberOptions;

@RunWith(Cucumber.class)
@CucumberOptions(
                features = "classpath:features",
                glue = {"com.vtiger.CucumberFramework.stepDefinitions","com.vtiger.CucumberFramework.testRunner"}, 
                plugin = { "pretty","html:target/cucumber-reports/cucumber-pretty", 
                           "json:target/cucumber-reports/CucumberTestReport.json",
                           "rerun:target/cucumber-reports/rerun.txt" },
                monochrome = true)

public class TestRunner {

}

Answer 1

make sure you have installed cucumber for eclipse from market place:

https://marketplace.eclipse.org/content/cucumber-eclipse-plugin

Goto preference and search for cucumber and enable step detection

Answer 2

The "glue" Cucumber option specifies the package where the step definition files are located. I don't think you need the runner package.

Try this:

@RunWith(Cucumber.class)
@CucumberOptions(
                features = "classpath:features",
                glue = "com.vtiger.CucumberFramework.stepDefinitions", 
                plugin = { "pretty","html:target/cucumber-reports/cucumber-pretty", 
                           "json:target/cucumber-reports/CucumberTestReport.json",
                           "rerun:target/cucumber-reports/rerun.txt" },
                monochrome = true)

public class TestRunner {

}

Answer 3

I faced a similar issue occasionally, Cucumber files fail to point to the associated step definition files even if it was working flawlessly previously.

One little hack is to go to the associated step definition class -> Make a harmless/Dummy modification -> Save the class file.

Now the eclipse feature files have no "Step does not have matching glue code" errors.
