code is a great way to give something back to the open source community. Before
you dig right into the code, there are a few guidelines that we need
contributors to follow so that we can have a chance of keeping on top of
things.

Some of the ideas are documented in the [Maven Wiki][maven-wiki]
which might be interesting to read and for further discussion.

     * Note: Project properties contains properties injected from profiles, if applicable. Their precedence is
     * {@code profile > project}, hence active profile property may override project property.

     * The caller of this method should decide whether there is a project in scope (hence, a project instance
     * needs to be passed) or not.

     * @param project {@link Project} or {@code null}.
