if you already use Spring and want to move your application to OSGi then
it's worth trying
does spring-osgi already use the maven-bundle-plugin?
yes, Spring-OSGi already uses the maven-bundle-plugin to wrap libraries and
build its bundles
btw, you might also want to look at the felix commons sub-project:
http://cwiki.apache.org/FELIX/apache-felix-commons.html
which provides poms to wrap various Java libraries as bundles.
