git commit stopped working - Error building trees

Question

I can not commit a change:

$ git commit
error: invalid object 100644 13da9eeff5a9150cf2135aaed4d2e337f97b8114 for \'spec/routing/splits_routing_spec.rb\'
err         


        

Answer 1

In my case, it is the file in remote branch that is broken. I solved it by:

1. remove the remote branches at all by $ git remote rm origin
2. add the remote back again: $ git remote add origin
3. fetch the remote again: $ git fetch origin
4. reset-hard to the desired branch on origin (say, develop): $ git reset --hard origin/develop

Then everything goes back to normal.
