Execute Cucumber tests from the cmdline via an executable JAR without Maven

Question

Here are the steps performed:

Step 1: Based on this, I built a standalone jar with all dependencies included using maven-shade-plugin.

pom.xml

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.22.2</version>
            <configuration>
                <testFailureIgnore>true</testFailureIgnore>
                <testSourceDirectory>${basedir}/src/main/java/</testSourceDirectory>
                <testClassesDirectory>${project.build.directory}/classes/</testClassesDirectory>
                <reportsDirectory>${project.build.directory}/test-output/${timestamp}</reportsDirectory>
            </configuration>
        </plugin>
        <!-- https://maven.apache.org/plugins/maven-shade-plugin/examples/executable-jar.html -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>3.2.1</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                    <configuration>
                        <!-- https://maven.apache.org/plugins/maven-shade-plugin/shade-mojo.html -->
                        <shadedArtifactAttached>true</shadedArtifactAttached>
                        <shadedClassifierName>standalone</shadedClassifierName>
                        <transformers>
                            <!-- https://maven.apache.org/plugins/maven-shade-plugin/examples/resource-transformers.html -->
                            <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                <mainClass>runners.RunCukesTest</mainClass>
                            </transformer>
                        </transformers>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

Added the main() method to the runner class and passed cmdline args based on this, this, and this.

RunCukesTest.java

package runners;

import cucumber.api.CucumberOptions;
import cucumber.api.SnippetType;
import cucumber.api.cli.Main;
import cucumber.api.testng.AbstractTestNGCucumberTests;

@CucumberOptions(features = { "src/main/resources/features" }, glue = { "steps" }, tags = { "not @ignore" }, plugin = {
        "pretty" }, monochrome = true)
public class RunCukesTest extends AbstractTestNGCucumberTests {

    public static void main(String[] args) {
        System.out.println("Begin running tests...");
        Main.main(new String[]{ "-g", "steps", "-t", "not @ignore", "-p", "pretty", "-m", "src/main/resources/features" });
    }

}

Step 2: Tried to run executable JAR.

λ java -jar project-xyz-1.0.0-standalone.jar
Begin running tests...
Exception in thread "main" java.lang.IllegalArgumentException: Not a file or directory: \path\to\jar\src\main\resources\features
        at cucumber.runtime.io.FileResourceIterator$FileIterator.<init>(FileResourceIterator.java:63)
        at cucumber.runtime.io.FileResourceIterator.<init>(FileResourceIterator.java:28)
        at cucumber.runtime.io.FileResourceIterator.createFileResourceIterator(FileResourceIterator.java:14)
        at cucumber.runtime.io.FileResourceIterable.iterator(FileResourceIterable.java:19)
        at cucumber.runtime.model.FeatureLoader.loadFromFeaturePath(FeatureLoader.java:112)
        at cucumber.runtime.model.FeatureLoader.load(FeatureLoader.java:48)
        at cucumber.runtime.model.FeatureLoader.load(FeatureLoader.java:30)
        at cucumber.runtime.FeaturePathFeatureSupplier.get(FeaturePathFeatureSupplier.java:22)
        at cucumber.runtime.Runtime.run(Runtime.java:68)
        at cucumber.api.cli.Main.run(Main.java:26)
        at cucumber.api.cli.Main.main(Main.java:8)
        at runners.RunCukesTest.main(RunCukesTest.java:17)

It reads the main() method in the runner class but throws

Exception in thread "main" java.lang.IllegalArgumentException: Not a file or directory: \path\to\jar\src\main\resources\features

UPDATE

It seems it is not reading the features directory inside the JAR.

Main.main(new String[]{ "-g", "steps", "-t", "not @ignore", "-p", "pretty", "-m", "src/main/resources/features" });

How do I point to the features directory inside the JAR via the cmdline args?

@mpkorstanje This worked! If you can post it as answer, I would be glad to upvote and accept as answer. — k_rollo, Oct 14 '19 at 23:05

You passed a relative path to Cucumber src\main\resources\features. Because you are executing the Jar this relative path is converted to an absolute path using the current working directory. However because src\main\resources\features is the source folder of your features, none could be found and you get:

Exception in thread "main" java.lang.IllegalArgumentException: Not a file or directory: \path\to\jar\src\main\resources\features

Instead you'll have to tell Cucumber that your features are on the class path. You do this by:

"classpath:features"
