Assume the following simple structure

pom.xml
src/test/java/TestRunner.java

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
    </properties>

            <scope>test</scope>
        </dependency>
    </dependencies>
</project>

TestRunner.java

import org.junit.runner.RunWith;

import cucumber.api.CucumberOptions;
import cucumber.api.SnippetType;
import cucumber.api.junit.Cucumber;

@RunWith(Cucumber.class)
@CucumberOptions(
        // add missing options here
        snippets = SnippetType.CAMELCASE
)
public class TestRunner {

}

Even the CucumberOptions is not filled completely you can run already the test.

$ mvn clean test

which produces following output

Running TestRunner
No features found at [classpath:]

Import this simple example in IntelliJ. If all other settings are correct you should be able to run it inside IntelliJ.

Answer 2

There are many reasons why this could be (you don't provide enough information).

But first, did you install the package? It is not contained in the standard jdk.

You can download and install cucumber via maven:

Visit https://maven.apache.org/ and https://docs.cucumber.io/installation/java/ for more Information.

I also faced this issue in eclipse and it gets resolved on adding java compiler source and target configurations under tag in POM.xml

The sample POM.xml is as follows:

Answer 4

I have also faced this issue that intelliJ is unable to resolve below dependencies:

import io.cucumber.junit.Cucumber;

import io.cucumber.junit.CucumberOptions;

import org.junit.runner.RunWith;

And there is nothing wrong with the pom.xml file the same project is working fine on ecllipse IDE while when I switched to IntelliJ, it was not able to resolve dependency. Looking on the internet I have found this link and added an extra dependency of "junit-vintage-engine" Please vote up if this helps.
