I would much rather see the Groovy stuff work the same way as the

Some BSF thing?
The 'BSF thing' is here: http://mojo.codehaus.org/script-maven-plugin/
I'm using this with some different languages and its working as
expected.
So I think that ideal situation would be to have one general plugin
like this (using BSF) so different languages may be used in basic
way (this would be a good replacement for using ant iniside maven
for some tasks). And, for advanced scripting: dedicated plugins
line ruby-maven-plugin, groovy-maven-plugin and so on.
Those plugins may also provide 'plugin-tools' so [groovy|ruby] driven
mojos may be created. I was planning to create such support
for BSF plugin too but... I think it will be better not to have BSF
layer - if somebody wants to write a plugin then I thing (s)he
would need direct access to interpreter.
I was aware of this plugin before, though it suffers from the basic
BSF limitation of lack of rich interaction with the underlying
scripting engine. Though as I mentioned before BSF is quite good for
simple expression evaluation, and nice and handy if you need to
expose the choice of language to users.
One of the issues right now with the groovy-maven-plugin, or your
plugin using BSF (or any BSF-thingy), its that with Groovy there is
no control over the GroovyClassLoader, which means that there is no
_easy_ way to allow scripts to import other scripts which happen to
live in the same directory or resource archive. This is easy enough
to resolve by adding a custom resource loader to the
GroovyClassLoader to fetch classes from.
Anyways... my point is (if I even have one) is that your script-maven-
plugin, and the more advanced script-specific plugins have their
place... I don't think that the BSF (or the new scripting muck in JDK
6... though I've yet to actually play with that much) provide a rich
enough interface for some of the more advanced bits one might want
for a scripting interface in Maven.
