For the UIMAJ project, we have two master branches: "master" for version 3, and "master-v2" for version 2.
Often, changes need to be applied to both. It seems there's a new-ish git functionality that supports this: git worktree. I haven't tried it, but might soon. If anyone else has, please respond with any experiential feedback. One thing I saw is that there may be issues using the git support in Eclipse. -Marshall
