I've been trying to understand the sequence of git operations which arrive at that state, and haven't yet understood them. My attempts have persuaded me that I don't understand submodules. I used my fork of the git-client-plugin for my experiments.

Clone the repository - works

git clone git://github.com/MarkEWaite/git-client-plugin
cd git-client-plugin
ls modules/ntp # reports an error, no content in modules/ntp



Checkout tests/getSubmodules - works





git checkout tests/getSubmodules
git submodule update --init --recursive
ls modules/ntp # Shows there is content in modules/ntp






Checkout master again - works





git checkout master # warns there are untracked files in modules directory
ls modules/ntp # shows content in modules/ntp is still there

git clean -xfd # skips modules/ntp and modules/firewall
ls modules/ntp # shows content in modules/ntp is still there

git clean -xffd # deletes modules/ntp and modules/firewall
ls modules/ntp # no content in modules/ntp






Checkout branch containing a conflicting file - works





git checkout tests/notSubmodules
ls modules/ntp # one file in modules/ntp






Checkout tests/getSubmodules again - works





git checkout tests/getSubmodules
git submodule update --init --recursive






Checkout branch (force) containing a conflicting file - works





git checkout -f tests/notSubmodules # works - but warns unable to rmdir
git clean -xffd
ls modules/ntp # one file in modules/ntp as expected






Checkout tests/getSubmodules (force) - fails





git checkout -f tests/getSubmodules
git submodule update --init --recursive
ls modules/ntp # one file in modules/ntp - should be more files there






The working sequence in my case seems to be "force checkout, then use git clean -xffd".  That doesn't work for the transition from "getSubmodules" to "notSubmodules", but covers the other cases.  Even a clean before checkout does not work for the transition from "getSubmodules" to "notSubmodules" (as far as I can tell).  However, since my case does not duplicate your message, I'm not sure if you'll see the same behavior as I see.



In that repository, the branch to branch transitions seem to behave like this:






Current Branch      
Branch to Checkout  
 Result 




 master              
 tests/getSubmodules 
 ok      




 master              
 tests/notSubmodules 
 ok      




 tests/getSubmodules 
 master              
 ok      




 tests/notSubmodules 
 master              
 ok      




 tests/getSubmodules 
 tests/notSubmodules 
 fails 




 tests/notSubmodules 
 tests/getSubmodules 
 ok      






However, the failure message I'm seeing is not the same as the failure message you're seeing.  I'm confident that means I don't understand enough about submodules.  Can you provide a similar series of steps (preferably using a fork of the git-client-plugin repository) to show your case?
