You also need Maven. We recommend 3.5 or newer. Building the documentation requires the `dot` utility from Graphviz. This is included in many Linux distributions. For other platforms see . **Full build** ```bash $ mvn install ``` **Checkstyle** ```bash # Cd to the component you want to check $ mvn validate -Pcheckstyle ``` **Copyright** ```bash # Cd to the component you want to check $ mvn validate -Pcopyright ``` **Spotbugs** ```bash # Cd to the component you want to check $ mvn verify -Pspotbugs ``` **Build Scripts** Build scripts are located in `etc/scripts`. These are primarily used by our pipeline, but a couple are handy to use on your desktop to verify your changes. * `copyright.sh`: Run a full copyright check * `checkstyle.sh`: Run a full style check ## Get Help * See the [Helidon FAQ](https://github.com/oracle/helidon/wiki/FAQ) * Ask questions on Stack Overflow using the [helidon tag](https://stackoverflow.com/tags/helidon) * Join us on Slack: [#helidon-users](http://slack.helidon.io) ## Get Involved * Learn how to [contribute](CONTRIBUTING.md) * See [issues](https://github.com/oracle/helidon/issues) for issues you can help with ## Stay Informed * Twitter: [@helidon_project](https://twitter.com/helidon_project) * Blog: [Helidon on Medium](https://medium.com/helidon)
