Error: Unable to access jarfile bfg.jar - BFG

Question

So I have mistakenly committed my secrets.yml in previous commits (yikes!!) and I want to clean my git commit history of it. It seems the fasted simplest way is to use BFG. I ha

Answer 1

2015: From the documentation, it should be:

java -jar bfg.jar  yourrepo

Try and use the full path of the jar if you have an error like "Unable to access jarfile bfg.jar": /home/user/path/to/bfg.jar.

If the jars are configured to be run with java, then /usr/local/bin/bfg would be the path of the symlink referencing the right bfg jar.

The alternative is described in "Remove sensitive data"

git filter-branch --force --index-filter \
'git rm --cached --ignore-unmatch Rakefile' \
--prune-empty --tag-name-filter cat -- --all

Or (update Nov. 2017), as commented by JeremyDouglass,

If you download the latest (e.g. from 1.12.16, the bfg-1.12.6.jar) and you only want to use standard commands in a local staging directory only (no path, no symlink), then you can simply rename the jar:

mv bfg-1.12.16.jar bfg.jar 
java -jar bfg.jar --delete-files bad.txt repo.git

2019-2020: more recently, you would now use You should use git filter-repo (that I mentioned here).

Install it first. (python3 -m pip install --user git-filter-repo)

Then, using a path-based filter:

git filter-repo --path secrets.yml --invert-paths HEAD

HEAD means it will change only your current branch commits.
Remove HEAD and it will go over all your commits in all your branches.
