NoClassDefFoundError: cucumber/api/DataTable when trying to upgrade to Cucumber 4

I am trying to upgrade my tests to Cucumber 4. I am using testNG and Maven.

I have updated my dependency versions for the following:

        <dependency>
            <groupId>io.cucumber</groupId>
            <artifactId>cucumber-java</artifactId>
            <version>${version.cucumber}</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>io.cucumber</groupId>
            <artifactId>cucumber-testng</artifactId>
            <version>${version.cucumber}</version>
        </dependency>
        <dependency>
            <groupId>io.cucumber</groupId>
            <artifactId>cucumber-guice</artifactId>
            <version>${version.cucumber}</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>io.cucumber</groupId>
            <artifactId>cucumber-jvm</artifactId>
            <version>${version.cucumber}</version>
        </dependency>

But I keep getting the error 'java.lang.NoClassDefFoundError: cucumber/api/DataTable' when trying to run a test.

This is my runner:

import cucumber.api.CucumberOptions;
import cucumber.api.*;
import cucumber.api.testng.AbstractTestNGCucumberTests;
import org.testng.annotations.DataProvider;

@CucumberOptions(plugin = {"XXXX"},
    features = "src/test/resources/features",
    glue={"XXXXX"},
    tags = {"@XXXXX"})

public class Cucumber4Runner extends AbstractTestNGCucumberTests {

    @Override
    @DataProvider(parallel = true)
    public Object[][] scenarios() {
        return super.scenarios();
    }

}

I have tried to ensure all versions of dependencies match up but struggling!

Most probably you have not aligned the import statements (other changes might be needed).

From the CHANGELOG.md

3.0.0 ... [Core] Replace DataTable with io.cucumber.datatable.DataTable (#1248 M.P. Korstanje, Björn Rasmusson, Marit van Dijk)

Based on your exception message your code is looking for cucumber.api.DataTable

edit There might be also a transient dependency from one of you other dependencies to an older cucumber version.

Assume the following dependencies only in your pom.xml

<properties>
    <version.cucumber>4.2.0</version.cucumber>
</properties>
<dependencies>
    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-java</artifactId>
        <version>${version.cucumber}</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-testng</artifactId>
        <version>${version.cucumber}</version>
    </dependency>
    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-guice</artifactId>
        <version>${version.cucumber}</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-jvm</artifactId>
        <version>${version.cucumber}</version>
        <type>pom</type>
    </dependency>
</dependencies>

listing the project dependencies 

$ mvn dependency:tree

would produce the following tree

[INFO] +- io.cucumber:cucumber-java:jar:4.2.0:test
[INFO] |  \- io.cucumber:cucumber-core:jar:4.2.0:compile
[INFO] |     +- io.cucumber:cucumber-html:jar:0.2.7:compile
[INFO] |     +- io.cucumber:gherkin:jar:5.1.0:compile
[INFO] |     +- io.cucumber:tag-expressions:jar:1.1.1:compile
[INFO] |     +- io.cucumber:cucumber-expressions:jar:6.2.0:compile
[INFO] |     \- io.cucumber:datatable:jar:1.1.7:compile
[INFO] |        \- io.cucumber:datatable-dependencies:jar:1.1.7:compile
[INFO] +- io.cucumber:cucumber-testng:jar:4.2.0:compile
[INFO] |  \- org.testng:testng:jar:6.14.3:compile
[INFO] |     +- com.beust:jcommander:jar:1.72:compile
[INFO] |     \- org.apache-extras.beanshell:bsh:jar:2.0b6:compile
[INFO] +- io.cucumber:cucumber-guice:jar:4.2.0:test
[INFO] \- io.cucumber:cucumber-jvm:pom:4.2.0:compile

Have a look if there is somewhere a dependency to

  • info.cuke:* any version
  • io.cucumber:cucumber-core version before 3
