I'm not sure exactly what the build dependencies are (I can't really read
jelly/jsl code that well) but I think some of the dependencies are handled
before we get to this step, since it the performJSL tag is called for
srcdir="${maven.gen.docs}" and srcdir="${maven.docs.src}" and the "uptodate"
check is called inside a j:forEach loop. So, I *think* some of the
dependencies you mentioned may have already been handled.
I'm pretty sure that the site.jsl and navigation dependencies should be handled
within this "uptodate" tag. I'm just not comfortable enough with the jelly,
jsl, etc. to be comfortable trying to handle all the dependencies.
The patch that I have does accelerate my build significantly when things
haven't changed, but there is a risk that someone could be burned by a
dependency not being handled and a source change not being reflected in the
generated site.
I went ahead and submitted a JIRA issue with a patch.
(http://jira.codehaus.org/browse/MPXDOC-141)
This is what I have so far, but hopefully someone who understands the XDOC
plugin better than me will improve the patch and apply it.
