Cucumber-JVM is a pure Java implementation of Cucumber that supports the following programming languages:
- Python (Jython interpreter)
- Ruby (JRuby interpreter)
Cucumber-JVM provides the following mechanisms for running Cucumber Features:
- Command Line
- JUnit (via IDE, Maven, Ant or anything that knows how to run JUnit)
Cucumber-JVM also integrates with the following Dependency Injection containers:
Downloading / Installation
Releases are published in Maven Central
Jar files can be browsed and downloaded from [Maven Central] or https://oss.sonatype.org/content/repositories/releases/info/cukes/ (New releases will show up here immediately, while it takes a couple of hours to sync to Maven Central).
Add a dependency in your POM:
<dependency> <groupId>info.cukes</groupId> <artifactId>cucumber-core</artifactId> <version>1.0.0-RC6</version> </dependency>
There are more jars available - add the ones you need. (TODO: A guide on how to pick the right jars needs to be written)
<dependency org="info.cukes" name="cucumber-core" rev="1.0.0-RC6"/>
Since the artifacts are released to Maven Central, the default Ivy configuration should pull them down automatically. Alternatively you can define your own resolver:
<ibiblio name="sonatype" m2compatible="true" usepoms="true" pattern="[organisation]/[module]/[revision]/[artifact]-[revision](-[classifier]).[ext]" root="https://oss.sonatype.org/content/repositories/releases/info/cukes/"/>
There isn't any documentation yet apart from API docs. Documentation will be published before the final 1.0.0 release is ready. If you are adventurous, check out the examples, read the code and ask specific questions on the Cucumber mailing list.
TODO: Fix this. The Ivy build doesn't upload them yet.

You will find an example in Git under examples/java-calculator. You should be able to run
basic_arithmetic.feature by running the
cucumber.examples.java.calculator.basic_arithmetic_Test JUnit test from your IDE. -Or simply by running it with Maven:
mvn clean install -P examples once to build it all. Then
cd examples/java-calculator followed by
mvn test each time you make a change. Try to make the feature fail!
The Ivy build is used primarily for making releases. It builds more artifacts than the Maven build does.
The secondary one is based on Maven. The Maven
pom.xml files are generated from the
ivy.xml files, and the main purpose of having a Maven based build is to make it easier to set up an IDEA or Eclipse project (by pointing to the root
You have to increase the memory first:
Now you can build it:
This will compile everything, run JUnit tests and Cucumber scenarios - and finally install all jars in your local Maven repo.
Before you can build with Maven you need to run the Ant+Ivy build once. This will generate some files that the Maven build is incapable of generating. Once that is done you should be able to build everything with:
mvn clean test
The top level directory has a
cucumber-jvm.ipr project file that references a
Just run ant once (see above) and install the IvyIDEA plugin.
Now, open the
cucumber-jvm.ipr project and you should be good to go.
(We might remove the
.iml files and recommend that people load the project by pointing to the root
Just load the root
To hack on Cucumber-JVM you need a JDK, Maven and Git to get the code. You also need to set your IDE/text editor to use:
- UTF-8 file encoding
- LF (UNIX) line endings
- 4 Space indent (no tabs)
- 2 Space indent (no tabs)
Please do not add @author tags - this project embraces collective code ownership. If you want to know who wrote some code, look in git. When you are done, send a pull request. If we get a pull request where an entire file is changed because of insignificant whitespace changes we cannot see what you have changed, and your contribution might get rejected.
Running cross-platform Cucumber features
All Cucumber implementations (cucumber-ruby, cucumber-jvm, cucumber-js) share a common set of Cucumber features to ensure all implementations support the same basic features. To run these you need to clone the cucumber-tck repo into your cucumber-jvm working copy:
git submodule update --init
Now you can run the cross-platform Cucumber features:
gem install bundler bundle install rake
Below are some common problems you might encounter while hacking on Cucumber-JVM - and solutions.
IntelliJ Idea fails to compile the generated I18n Java annotations
This can be solved by changing the Compiler settings:
Preferences -> Compiler -> Java Compiler:
- Use compiler:
Javac in-process (Java6+ only)
- Additional command line parameters:
-target 1.6 -source 1.6 -encoding UTF-8
Fork the repository on Github, clone it and send a pull request when you have fixed something. Please commit each feature/bugfix on a separate branch as this makes it easier for us to decide what to merge and what not to merge.
