You actually shouldn't really have to do anything. The Daffodil CLI orders the
classpath so it its own jars go before anything provided in DAFFODIL_CLASSPATH,
and thus have precedence.
So, for example, if you add daffodil-lib-3.8.0.jar to DAFFODIL_CLASSPATH but you
are running with Daffodil CLI 3.9.0, that 3.8.0 jar will just be ignored and the
daffodil-lib-3.9.0.jar will be used.

Thanks for this. However, right now plugins seem to drag in dependencies on
the version of daffodil they were compiled with.
This is fixed in the next (as yet unreleased) sbt-daffidil, but how do I
cope with this in the short term?
If I do 'sbt "export fullClassPath"' I will get a mixture of different
daffodil jars, or entirely wrong ones it seems.
Do I just edit this classpath by hand so I can set DAFFODIL_CLASSPATH
properly, or is there a better workaround?

I just responded to the other thread related to this, but more succinctly:
For modern versions of Daffodil you shouldn't need different plugin
versions for
different Daffodil versions.
A charset plugin will work with all version of Daffodil 3.4.0 or newer
A layer plugin will work with all versions of Daffodil 3.8.0 or newer
A UDF plugin will work with all versions of Daffodil 3.0.0 or newer
I suggest only including a daffodil version in the name or version of a
plugin
if you are maintaining a plugin for use with an older version of Daffodil
than
listed above. It should not be needed for newer versions of Daffodil as
long as
we continue to maintain backwards compatibility. And I think our APIs are
stable
enough that this shouldn't be a problem.
So if you want a charset plugin to work with 3.8 and 3.9, you can built it
with
an modern version of Daffodil and the jar should work with all of them.
Note
that if this isn't the case, it means we probably have a bug somewhere, or
maybe
I have the version numbers off.

This is true of all our plugins, layers, UDFs, etc.
But the jar file created when compiling them is not named differently for
different versions of daffodil.
That suggests that I need to have different versions for different
versions
of daffodil, e.g.,
version 1.1.380 for daffodil 3.8.0, and version 1.1.390 for daffodil
3.9.0
Or am I missing something about how to do this?
