Maven Artifacts

This article talks about the Maven repos, and the various artifacts we publish.

Public Maven Repositories

WPILib maintains 2 public Maven repositories: development and release. These repositories are available at http://first.wpi.edu/FRC/roborio/maven/<release channel>, where <release channel> is substituted by the repository you want to use. For developing WPILib, this defaults to development. However, you are free to use the release channel during the season if you want to use an alternative build system such as Maven or Gradle. However, note that we cannot provide official support for build issues if you take this route.

These repositories are browsable with your web browser: simply navigate to the URL of your chosen repository. Note that there are a few dependencies in the top level (first.wpi.edu/FRC/roborio/maven). These are there for legacy purposes and are not updated: you should not attempt to depend on them.

For each of our Maven artifacts, we use one of 2 versioning schemes, both based on semantic versioning (semver.org). The first scheme is unmodified semantic versioning (referred to as semver in the artifacts list below). The other versioning scheme is similar, but has the following structure: <season>.<mandatory update>.<optional update>. So, the first release of the 2017 season will have the version 2017.1.1. If an optional update was released, the new artifacts would have the version 2017.1.2. If a mandatory update was then released, it would have the version 2017.2.1. This versioning scheme will be referred to as wpilibver in the artifact listing below.

Artifacts

The following is a listing of the available Maven artifacts (build products). The format for each of these listings is as follows: package-id:artifact-id:versioning scheme - Description, including the project and repository it is published by. All artifacts are jar files, unless otherwise specified.
