This is going to sound like an odd, possibly stupid question. When I
run 'mvn install' on a multi-project, maven will loop through the
projects in the list. It appears that even though most of the jar
projects have no changes, it rebuilds each jar. Obviously the compiler
leaves the classes alone unless I do a clean first, but the jar gets
built each time. I would imagine things would be faster if this didn't
happen.
Same with the war plugin.
Normally this might not be big deal, but I've implemented war
composition with webapps. It'll leave the dependent wars alone if
they're older, but if not it'll extract, then rebuild the whole thing.
Because 'mvn install' is building the final outputs each time, even if
things haven't changed, each webapp build is doing the full extract and
re-package.
However, this seems like a fairly general question. Its also quite
possible that I'm doing something strange.
Thanks in advance,
