Actually, all hope is not lost.
First off, if you unpack the module, you will see that the Java sources custom modules is in the sub-directory source (kudo’s to @pdietrich2 for providing the sources). You can ignore the sub-directory source/com as that code isn’t used in the module (in fact, you should probably remove that sub-directory).
Secondly, the file source/net/cantab/hayward/george/OCS/edits.required shows you the translation from standard Vassal elements to the custom elements. The file contains sed regular expression substitutions, and the script source/net/cantab/hayward/george/OCS/exec.edits shows you have these are executed. If you reverse these regular expressions - e.g.,
s/VASSAL.build.module.BasicCommandEncoder/net.cantab.hayward.george.OCS.BasicCommandEncoderOverride/g
to
s/net.cantab.hayward.george.OCS.BasicCommandEncoderOverride/VASSAL.build.module.BasicCommandEncoder/g
and then execute source/net/cantab/hayward/george/OCS/exec.edits then that will revert the module to the standard Vassal elements.
Of course, that will mean a loss of functionality in the module.
So, a better way is to fix the custom code and recompile it (see also Simple Workflow). Assuming you have installed VASSAL in /opt/vassal/current (on Linux), do
cd source
javac -cp /opt/vassal/current/lib/Vengine.jar --release 11 `find net -name "*,java"`
and when that compiles cleanly, copy the generated .class files (with directory structure) to the root of the unpacked archive
tar -cf - `find . -name "*.class"` | tar -xf - -C ..
Of course, any errors in the custom code need to be fixed first:

Most of these seem relatively simple to fix, e.g., Labeler.CENTER is now 'c', and PlayerRoster.addSideChangeListener seems now to be PlayerRoster.getInstance().addSideChangeListenerToInstance. Other issues may take a bit more thought. Note, warnings can be ignored for now, although deprecation warnings will be needed to be addressed for the module to work with future Vassal releases.
