Resolution: Cannot Reproduce
Jenkins is looking for a "CVS" directory in the workspace. Since it does not find this (it is not supposed to - multiple modules/legacy option checked), it tries another build, and another and another and so on.
In the example above, "C:\Program Files (x86)\Jenkins\workspace\Common" is the path to the workspace, and contains other folders that are the actual modules for the build:
C:\Program Files (x86)\Jenkins\workspace\Common\libAlpha
C:\Program Files (x86)\Jenkins\workspace\Common\libMath
C:\Program Files (x86)\Jenkins\workspace\Common\commonLib
C:\Program Files (x86)\Jenkins\workspace\Common\mainApp
This is also on an issue on linux slaves, without spaces in the path.
