Building
--------

Building requires a Java JDK and [Apache Maven](https://maven.apache.org/). 
The required Java version is found in the `pom.xml` as the `maven.compiler.source` property.

From a command shell, run `mvn` without arguments to invoke the default Maven goal to run all tests and checks.

Contributing
------------

We accept Pull Requests via GitHub. The [developer mailing list](https://commons.apache.org/mail-lists.html) is the main channel of communication for contributors.
There are some guidelines which will make applying PRs easier for us:
+ No tabs! Please use spaces for indentation.
+ Respect the existing code style for each file.
+ Create minimal diffs - disable on save actions like reformat source code or organize imports. If you feel the source code should be reformatted create a separate PR for this change.
+ Provide JUnit tests for your changes and make sure your changes don't break any existing tests by running ```mvn```.
