This is a good question. Normally, I'd look at the jira project which would link back to the Maven project web pages.
The summary jira page https://issues.apache.org/jira/browse/MNG?selectedTab=com.atlassian.jira.jira-projects-plugin:summary-panel doesn't describe MNG components well enough to find them. The summary pages for each component doesn't link to a Maven project web page. If you select any issue, and then its Activity tab, you might get lucky and get a Hudson notification. And in the Hudson job you can find the git url in the Git Polling Log page. In this case https://git-wip-us.apache.org/repos/asf/maven.git which is all Maven Core. I'm behind an NTLM firewall at work so I've avoided working with git and Maven. Hopefully someone else can provide an answer, and then we can update the documentation to better reflect that. ---------- Forwarded message ---------- From: Benjamin Chylla <ejbga...@gmail.com> Date: 6 August 2015 at 00:53 Subject: Re: [ANN] 2015 Committer School for people who want to become Maven Committers To: Maven Developers List <dev@maven.apache.org> Hello, I have a question. I am trying to use Git in order to work with the source code in the Maven Respository. When I find a Maven project issue on JIRA, how do I determine which GitHub repository to make a fork of? >From my understanding, https://git-wip-us.apache.org/repos/asf/maven.git is the location of the main git repository for Maven, but there is also a separate repository for the integration tests for the Maven core (https: //git-wip-us.apache.org/repos/asf/maven-integration-testing.git), as well as other components (Archetype, Indexer, Plugin Testing, SCM, Surefire, and Wagon). For example, one of the open JIRA issues that I am interested in working on has the following components listed: Embedding <https://issues.apache.org/jira/browse/MNG/component/12325608>, General <https://issues.apache.org/jira/browse/MNG/component/12325623>, Logging <https://issues.apache.org/jira/browse/MNG/component/12325605>,Performance <https://issues.apache.org/jira/browse/MNG/component/12325616>, Reactor and workspace <https://issues.apache.org/jira/browse/MNG/component/12325615>. There are two other issues that I am interested in; one displays "Dependencies" after "Component/s", while the other displays "None." I would also like to know whether the "Affects Version/s" section is important. I am using Maven 3.3.3 on my machine. Is it important to use a version of Maven that closely matches the affected version?
