Start Contributing

Before you start working on Apache Ignite, you should sign up to the dev mailing list and say "Hello" to everyone in the community. We have a very friendly group and intend to make joining the project as easy as possible.

Note, you need to subscribe to the dev list, before sending emails to it. To subscribe, send an empty email to dev-subscribe@ignite.apache.org and follow simple instructions in the reply.

You should also sign up to Ignite Jira and browse through open tickets.

Before you start contributing, it helps to familiarize yourself with Ignite Development Process.

• Choose any of the tickets below.
• Send an email to the dev list letting us know that you want to work on it (make sure to subscribe first).

Start Developing

Apache Ignite uses GIT for its VCS system. The "master" branch contains the last released version. The "sprint-N" branch contains the latest code for the Nth sprint.

                # Master branch.
                $ git clone https://git-wip-us.apache.org/repos/asf/ignite

                # Release branch.
                $ git clone https://git-wip-us.apache.org/repos/asf/ignite -b ignite-1.3.0
            

                # Build project.
                $ mvn clean package -DskipTests

                # Run Apache RAT
                $ mvn clean validate -Pcheck-licenses
            

See more detailed build instructions in the DEVNOTES.txt file.

Become a Committer

We love contributions and gladly promote active contributors to committers and PMC members!

The most important point of becoming a committer for Apache projects is active participation within the community. Being an active community member means participating on mailing list discussions, helping to answer questions, being respectful towards others, and following the meritocratic principles of community management.

Of course, code contributions are also important. Once you make a few code contributions, you will become eligible to join Ignite committers, and possibly Ignite PMC. Candidates for new committers or PMC members are suggested by the current committers, mentors, or PMC members, and then must be approved by the PMC voting process.
