The Phonelocator project, git://github.com/alexbirkett/phonelocator-android.git, has the following submodules:

[submodule "HockeyKit"]
path = HockeyKit
url = git://github.com/alexbirkett/HockeyKit.git
[submodule "cwac-locpoll"]
path = cwac-locpoll
url = git://github.com/alexbirkett/cwac-locpoll.git
[submodule "ActionBarSherlock"]
path = ActionBarSherlock
url = git://github.com/alexbirkett/ActionBarSherlock.git
[submodule "android-controllers"]
path = android-controllers
url = git://github.com/alexbirkett/android-controllers.git

The first time Jenkins builds the project, everything appears to be checked out in the correct place. On subsequent builds, corruption occurs and files from one or more of the submodules appear in the root directory of the workspace.
