Hi Sander,
That was a big help! Thanks. And yes, surrounding the property in single quotes
solved the problem. For example: -Dexcludes='${project.groupId}’
FWIW, the ${groupId} form did work (so I don’t think BASH was substituting the
empty string because no such environment variable existed).
Mystery solved, not a maven issue, just my misuse of bash.

Hi,
Seems like your property is interpreted by BASH, which I don't think is what
you want.
${BLAH} is a BASH variable, mostly equivalent to $BASH. I think what you meant
is '${BLAH}', i.e. not substituted by BASH, giving Maven a chance to
substitute. FYI, you wouldn't want "${BLAH}" either (with double quotes BASH
will still substitute).
${BLAH.BLAH} is an invalid BASH variable, due to the period, hence its balking.
Your ${groupId} probably "works" in the sense that BASH doesn't complain. I
don't think that it works in the sense that Maven substitutes it for the actual
groupId. I don't think that it'll get the chance for that, because likely BASH
already substitutes it for an empty string (assuming it doesn't know a groupId
variable in your environment; not entirely sure on basis of the limited
information given).
Hope this helps.
