Transition project Metropolis to Git, GitHub and Skara

[Vladimir Kozlov]

Hi all,

You might have heard that there is an OpenJDK project named Skara evaluating and trialing using Git for OpenJDK and 
GitHub for hosting the repositories [1]. We have been asked to try out Git, GitHub and the Skara tooling, as a means of 
validating, and to provide feedback about the Project Skara effort. There is already a number of OpenJDK projects using 
Git, GitHub and Skara:
- OpenJFX
- OpenJMC
- Loom
- Panama (the "foreign" branches)
- Valhalla (the "lworld" branch)
- Mobile

A transition entails switching to Git as an SCM [2] and the repository would be hosted on GitHub [3]. After the 
transition, the current Mercurial repository would no longer be updated. There is currently already a read-only mirror 
of Metropolis in place [4], you can it use to try out Git and some of the tooling, though submitting pull requests and 
pushing will not work (as it is a read-only mirror).

I suggest that project Metropolis transition to git, GitHub and Skara and that we set the target date for the transition 
to March 18. Given that project Metropolis still is in a prototype phase I do *not* suggest that we adopt pull requests, 
but instead do like project Loom and push directly to the Git repository on GitHub [4].

Project Skara also provides CLI tools for interacting with Git and GitHub for those that prefer working from a terminal. 
You can find more info about these tools on the Skara wiki page [6].

If you have any comments or questions regarding this transition, please reply to this thread.

Thanks,
Vladimir
