I have recently started to look into android development (aosp) and read about "repo" tool/wrapper that takes care of all the android's sub projects .
While I think repo does a fairly good job at what it does, I wanted to know if there are any alternatives to it.
I thought git submodules are sufficient for this but many posts on internet discourage use of submodules ( due to some "drawbacks" which I feel are not drawbacks at all ).
Keeping in mind that the source code for different sub projects should have their own releases or indipendednt code bases I am not sure if git subtree is a good solution for this.
It would be great if someone can point out some alternatives to repo or any other information about this.
repo has one huge disadvantage: it detaches HEADs. You can't switch to specific branch under specific subrepo. Unless you do repo start
tsrc, as far as I know, has less functionality but doesn't have this specific problem.
Also, you can use embedded mechanisms of build systems like Bazel (git_repository/new_git_repository).
