The Maven-Sling-Plugin may be used to install a bundle into a running
sling instance. Currently, this only uploads the bundle (and installs or
updates it) but does not refresh the packages, which is required for
updated bundles, which were used by other bundles.
I suggest we enhance the sling plugin to by default refresh the packages
on an update. This functionality may be switched off by setting a system
(or configuration) property.
