modelVersion. This is required so that a change from modelVersion 4.0.0 to
  4.1.0 doesn't cause compatibility problems with users who have not upgraded
  their projects. It also allows for a certain amount of legacy support into the
  future. Therefore, we should rename this file from pom.xml in the maven-core
  jarfile to pom-4.0.0.xml (and successive revisions to the base pom made to

    license or settlement) prior to the initiation of patent
    infringement litigation, then the reasonable value of the licenses
    granted by such Participant under Sections 2.1 or 2.2 shall be taken
    into account in determining the amount or value of any payment or
    license.

    6.4. In the event of termination under Sections 6.1 or 6.2 above,
    all end user licenses that have been validly granted by You or any

Getting Started
---------------

+ Make sure you have a [JIRA account](https://issues.apache.org/jira/).
+ Make sure you have a [GitHub account](https://github.com/signup/free).
+ If you're planning to implement a new feature, it makes sense to discuss your changes
  on the [dev list](https://maven.apache.org/mailing-lists.html) first.
