Contributing to Apache Maven Artifact Plugin

Apache License, Version 2.0, January 2004 Maven Central Reproducible Builds Jenkins Status Jenkins tests

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.

This plugin contains compare goal for Reproducible Builds tooling, to ease checking Maven builds that are expected to be reproducible get really the same output as reference build.

The purpose of this compare goal is:

  • to generate a buildinfo file from a build, recording fingerprints of output files

  • compare this recording of outputs to the reference files.

Comparing local build against remote reference

If reference build is available in a remote repository with predefined id, like central:

mvn verify artifact:compare -Dreference.repo=central

If reference build is available in a remote repository without predefined id, use its url instead:

mvn verify artifact:compare -Dreference.repo=https://repository.apache.org/content/groups/maven-staging-group/

Getting Started

  • Make sure you have a GitHub account.
  • If you‘re planning to implement a new feature, it makes sense to discuss your changes on the dev list first. This way you can make sure you’re not wasting your time on something that isn‘t considered to be in Apache Maven’s scope.
  • Submit a ticket for your issue, assuming one does not already exist.
    • Clearly describe the issue, including steps to reproduce when it is a bug.
    • Make sure you fill in the earliest version that you know has the issue.
  • Fork the repository on GitHub.

Making and Submitting Changes

We accept Pull Requests via GitHub. The developer mailing 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.
  • Make commits of logical units.
  • Respect the original code style: by using the same codestyle, patches should only highlight the actual difference, not being disturbed by any formatting issues:
    • Only use spaces for indentation.
    • Create minimal diffs - disable on save actions like reformat source code or organize imports. If you feel the source code should be reformatted, create a separate PR for this change.
    • Check for unnecessary whitespace with git diff --check before committing.
  • Make sure you have added the necessary tests (JUnit/IT) for your changes.
  • Run all the tests with mvn -Prun-its verify to assure nothing else was accidentally broken.
  • Submit a pull request to the repository in the Apache organization.

If you plan to contribute on a regular basis, please consider filing a contributor license agreement.
