# Requirements

* JDK 11
* Apache Maven 3.x
* A modern Linux, OSX, or Windows host

<a name="building"></a>
# Building the sources

You can build and verify the sources as follows:

    ./mvnw verify

`verify` goal runs validation and test steps next to building (i.e., compiling) the sources.
To speed up the build, you can skip verification:

    ./mvnw -DskipTests package

If you want to install generated artifacts to your local Maven repository, replace above `verify` and/or `package` goals with `install`.

## DNS lookups in tests

Note that if your `/etc/hosts` file does not include an entry for your computer's hostname, then
many unit tests may execute slow due to DNS lookups to translate your hostname to an IP address in
[`InetAddress.getLocalHost()`](http://docs.oracle.com/javase/7/docs/api/java/net/InetAddress.html#getLocalHost()).
To remedy this, you can execute the following:

    printf '127.0.0.1 %s\n::1 %s\n' `hostname` `hostname` | sudo tee -a /etc/hosts

<a name="website"></a>
# Building the website and manual

You can build the website and manual as follows:

    ./mvnw site

And view it using a simple HTTP server, e.g., the one comes with the Python:

    python3 -m http.server -d target/site
