# How to build PMD

PMD uses [Maven](https://maven.apache.org/) and requires [Java 9](http://www.oracle.com/technetwork/java/javase/downloads/index.html)
for building.

PMD uses the [maven wrapper](https://github.com/takari/maven-wrapper), so you can simply build PMD as following:

*   `./mvnw clean verify` (on Unix-like platform such as Linux and Mac OS X)
*   `mvnw.cmd clean verify` (on Windows)

This will create the zip files in the directory `pmd-dist/target`:

    cd pmd-dist/target
    ls *.zip

That's all !

**Note:** While Java 9 is required for building, running PMD only requires Java 7 (or Java 8 for Apex).

## How to build the documentation?

    cd docs
    bundle install # once
    bundle exec jekyll build

You'll find the built site in the directory `_site/`.
