Is it possible to slim a .git repository without rewriting history?

Question

We have a number of git repositories which have grown to an unmanageable size due to the historical inclusion of binary test files and java .jar fi

Answer 1

I don't know of a solution which would avoid rewriting the history.

In that case, cleaning the rpeo with a tool like BFG- repo cleaner is the easiest solution (easier that git filter-branch).
