I will first fix PAXURL-144 and update in Karaf, before dealing with this one.

> 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.

>         <bundle>mvn:com/example/dependency/1.0.0</bundle>

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