Can I detect the change of sub project?

Question

I'm building up C.I system for my project. My project is managed by Git and has two sub modules. I found that teamcity cannot detect the change of submodule. Is there any way to detect the change of submodule without setting up additional C.I projects?

Answer 1

As mentioned by another user in this answer:

You could add a step which will checkout, from the parent repo, if a submodule has any modified file.

As mentioned in that answer, to checkout you could do:

To undo all changes to your submodule just cd into the root directory of your submodule and do git checkout .

For the shorter method you could do git submodule foreach --recursive git checkout.

Answer 2

Does your submodule require authentication? There are number of issues in the tracker that might cause this behaviour: TW-35594, TW-34281, TW-23300, TW-24809
