I am pretty new to JGit and git in general so this question may come of as noobish. Here is what I want to achieve:

For a particular commit, expose its source tree as an in-memory filesystem and add it to a certain classpath. I want to avoid shelling to git, checking out the commit and adding the git project's directory to classpath because of the implications of a dirty working directory. Is this doable with JGit?

- use a RevWalk to travel to the RevCommit you want
- get the commit's tree ("the file system of this version")
- use a TreeWalk to walk the version's filesystem tree
