Alan,
I think I now have a working, if not elegant, solution.

This appeared to make no difference - I'm guessing that the fact one
target was plplot.jar and one was
${CMAKE_CURRENT_BINARY_DIR}/plplot.jar was the reason. I agree it is
dangerous though so I've changed it.

Investigation showed that cross-directory depends do work, at least in
this case. I have manually added the list of .class files from
plplot/core to the DEPENDS for ${CMAKE_CURRENT_BINARY_DIR}/plplot.jar
and this appears to correctly rebuild.
Not the prettiest solution, but it works, and no need to rebuild the
.jar file every time.
