To manage them, you now probably have some criteria they have in
common. Maybe there is a list or all  are in a specific subdirectory
or in a ZIP, allowing you to iterate the list, copy the directory or
unzip it?
For Java, sometimes a source code generation tool (small perl script
or so) can be of great help, especially for defining many specific
Exception (and keeping it DRY :)).

In some modules we have some hundred files which are imported from
another source. During the import we create some filelist.mak:

echo "# Autogenerated by $0"  > ${_mak}
echo "${module}files = \\"         >> ${_mak}
find directoty1 directory2 directory3 -type f \
   -not -path '*/CVS*' \
   -not -path '*/*.sw?' \
   -exec echo "{} \\" \; \
                  | sort    >> ${_mak}
echo "${_mak}"              >> ${_mak}

Also find and friends could be used in Makefile rules but we made less
good experiences with it; at least errors can be hard to find because
may turn out much later and it feels "less defined" I think.

just in the hope to possibly give some inspiration.
