Making and Submitting Changes
--------------

We accept Pull Requests via GitHub. The [developer mailing list][dev-ml-list] is the
main channel of communication for contributors.  
There are some guidelines which will make applying PRs easier for us:
+ Create a topic branch from where you want to base your work (this is usually the master branch).
  Push your changes to a topic branch in your fork of the repository.

        // before because with parents as ranges it will never work in this scenario.
        //

        String artifactId = candidateModel.getArtifactId();

Extending the POM in the future

  In order to anticipate changes in the structure of the POM as new releases of
  maven occur, the maven inheritance model must be pinned against a particular
  modelVersion. This is required so that a change from modelVersion 4.0.0 to

    /**
     * Checks whether the current Maven runtime matches the specified version range. A version range can either use the
     * usual mathematical syntax "[2.0.10,2.1.0),[3.0,)" or use a single version "2.2.1". The latter is a short form for
     * "[2.2.1,)", i.e. denotes the minimum version required.
     *
     * @param versionRange The version range to match the current Maven runtime against, must not be {@code null}.

        // ...
        //
        // And the range is not set so we'll check here and set it. jvz.

        if (range == null) {
            range = VersionRange.createFromVersion(artifact.getVersion());
        }
