currently embedded dependencies are added to the Include-Resource
statement after the maven resources - unfortunately this means that any
inlined entries will overwrite local entries, which isn't optimal

I'll change this ordering round in 1.4.1 (open a JIRA issue to remind me)

you'll also be able to customize the Include-Resource better in 1.4.1, eg:

<Include-Resource>

{maven-dependencies},some-file,{maven-resources},another-file
</Include-Resource>

where {maven-dependencies}

and

{maven-resources} expand to the list of
embedded entries and maven resources respectively - you can already do
this to some extent with 1.4.0, but there's a bug on Windows with replacing
the "{maven-dependencies}" token...

so the workaround with 1.4.0 would be to use something like this in place
of the Embed-Dependency - you'll need to list each dependency explicitly
using @artifactId-version.jar to inline it (this is what Embed-Dependency
does under the covers) for example:

<Include-Resource>
@jsf-impl-1.2-b19.jar,{maven-resources}

</Include-Resource>

will inline the JSF jar and then overlay resources from the current project
