Contributing to Apache Maven
======================

You have found a bug or you have an idea for a cool new feature? Contributing
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]

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

If you are interested in the development of Maven, please consult the
documentation first and afterward you are welcome to join the developers
mailing list to ask questions or discuss new ideas/features/bugs etc.

Take a look into the [contribution guidelines](CONTRIBUTING.md).

 Typically users parameterize the use of plugins, or have custom values like ${user.name}
 for use in elements like the <developerConnection/>. It would be idea if we
 could encapsulate everything we need about the project in the POM including
 plugin parameters and anything else.

 We once had a document that Vincent and I agreed upon and I was about to

        return merger.merge(child, parent, false, hints);
    }

    /**
     * Calculates the relative path from the base directory of the parent to the parent directory of the base directory
     * of the child. The general idea is to adjust inherited URLs to match the project layout (in SCM).
     *
     * <p>This calculation is only a heuristic based on our conventions.
     * In detail, the algo relies on the following assumptions: <ul>

                                // versions. We just clobbered the selected version above. (why? I have no idea.)
                                // So since we are here and this is ranges we must go figure out the version (for a
