When there are nested projects in a manifest, like on AOSP right now: <project path="build" name="platform/build" /> <project path="build/blueprint" name="platform/build/blueprint" /> <project path="build/kati" name="platform/build/kati" /> <project path="build/soong" name="platform/build/soong" /> And the top "build" project is removed (or renamed to remove the nesting), repo just wipes away everything under build/ and re-creates the projects that are still there. But it only checks to see if the build/ project is dirty, so if there are dirty files in a nested project, they'll just be blown away, and a fresh worktree checked out. Instead, behave similarly to how `git clean -dxf` behaves and preserve any subdirectories that have git repositories in them. This isn't as strict as git -- it does not check to see if the '.git' entry is a readable gitdir, just whether an entry named '.git' exists. If it encounters any errors removing files, we'll print them all out to stderr and tell the user that we were unable to clean up the obsolete project, that they should clean it up manually, then sync again.

repo
Repo is a tool built on top of Git. Repo helps manage many Git repositories, does the uploads to revision control systems, and automates parts of the development workflow. Repo is not meant to replace Git, only to make it easier to work with Git. The repo command is an executable Python script that you can put anywhere in your path.
