How to change url/path of a submodule

For me the solutions I found did not work, because the git history of my repository is completly different from the history of the new repository.

Let me explain. I received a project as a Zip file. I initialized a fresh repo and commited the files and pushed it to my bitbucket.

Then I found out, that it is a public github project. So I wanted to change the URL to the github repository. But they have completly different git histories (My repo just has an initial commit, while the github repo contains all commits.)

So it won't work by just changing the URL's.

So I had to delete the submodule and create it again.

Hint: <name_of_submodule> = app/code/EthanYehuda/CronjobManager (in my case)

Delete:

git submodule deinit <name_of_submodule>
git rm -f <name_of_submodule>
rm -rf .git/modules/<name_of_submodule>
git commit -m "Deleted submodule xy"

Re-Add:

git submodule add --force https://github.com/example/foo-bar.git <name_of_submodule>
git commit -m "Add submodul xy"

Fetching submodule app/code/EthanYehuda/CronjobManager error: The server refused requests to not specified object 9b677ef0e750acb9292030306bd97a3ee2734c61

↑ If an error like this shows up after pulling the project on a clone e.g. staging, then you have to sync and update --init after git pull:

git submodule sync
git submodule update --init
