---------------------------------------
I noticed that the codebase has had some grooming but the patches still apply with trivial adjustments.

> Eclipse M2E plugin provides a 'workspace resolution' mode where Maven projects in Eclipse workspace are provided as workspace repository which takes precedence over other repositories.
> This leads to situation where artifact file isn't necessarily yet - depending on Mavens current lifecycle phase - provided as .jar but instead as directory pointing to project's output directory.

> The patches provided in this issue not only takes care of treating directories as exploded .jar files (common approach) but also provisions them with reference: protocol that most of the OSGi frameworks understand as direct filesystem references thus allowing exploded .jars to be installed.

> ...
> <bundle>reference:file:/~/workspace/example-project/classes/</bundle>

> </features>

> Without intermediate round-trip via OSGi framework's bundle cache the 'workspace resolution' mode now offers also hot code replacement.
