I have a local git repository on my Mac that is managed by Xcode. I recently created a new branch and have made a lot of changes since then. I was about to perform my first commit to this new branch and was presented with an error dialog:
The working copy "app name" failed to commit files.
error: invalid object 100644
888688965... for 'Supporting Files/animage.png'
error: Error building trees
I searched the Interwebs for a solution and found this question which appears to be the same issue. I tried both answers to this question and neither solved the problem for me. I have done everything I can think of to solve the problem but have not been successful.
- I tried looking for the problematic file as the answer suggested but there are no files in /repo/.git/objects/88. I also looked in backups (I have hourly Time Machine backups) but there never were files in that folder.
- I tried
git reset --hardand this removed uncommitted changes, but after doing so I cannot commit a simple change. The exact same error message is presented. - I tried to trash the image referenced in the error message, but then the next time I attempt to commit the same error is displayed referencing a different image. After trashing all images it started listing code files.
- I tried creating a new branch and committing to that branch, but the same error is presented.
- I switched to my other partition where I previously worked on this project (the files sync over Dropbox which may have been the cause of the problem) and attempted a commit only to experience the same error message.
- I finally decided to restore the entire project to an earlier point in time, I went back two months ago before I even made any branches, yet still a simple commit refuses to work. This makes me believe an external factor is involved, something outside of the project folder. I know it worked back then so this has me very confused. This is the error presented:
The working copy "app name" failed to commit files.
fatal: unable to read tree 781d...
After running git fsck --full I see there are several broken links from trees, a lot of dangling blobs, several missing blobs, and two missing trees.

After attempting to clone the repo, this is what is logged:

warning: Clone succeeded, but checkout failed.
At this point in time I am willing to do anything to prevent having to trash the entire git repository and start over. I don't want to lose my branches and history. How can I fix this issue? I have a working copy of the project directory exactly as it was when I first discovered the error as well as Time Machine backups for the entire history of this project. Anything you can suggest is appreciated.
