In previous week, I have published this blog post about creating a git submodule as a new git repository by preserving commit history.
After this change in one of our games, it was necessary to update our compile and build jobs defined on jenkins service in our build machine. When you configure your jenkins job, you will see “Additional Behaviours” option in your build section as follows :
Click on the Add button and select “Advanced sub-modules behaviours” option.
Now the following section has been added into your build area and you should select “Recursively update submodules” checkbox.
Ok, everything seems ok but when you build your job, you will see some error messages about git credentials as follows :

Finished: FAILUREI know you expect that the same username and password will be used while cloning the submodule, but jenkins won’t be able to do this due to this bug which is reported and still open.
The easiest workaround for this issue is that entering your own credentials manually during the first time cloning for your jenkins job. You can see the directory that jenkins created for your job in your error message :
/Users/admin/Jenkins/workspace/Game-Compile-With-SubmoduleGo to this directory and run those commands for initializing your submodule for the first time :
git submodule init
git submodule updateNow cloning process is over and you can run your jenkins job successfully. It won’t ask your credentials again, but please remember that you should apply same steps again if you create a new jenkins job with a git submodule.
