I'm trying to use the Karaf maven plugin to build a custom Karaf distribution
(so "karaf-assembly" packaging type)
I'm stuck on the following error though:
Failed to execute goal

I have the org.apache.karaf.features:enterprise feature as a dependency (along
with framework, standard, spring), so I believe that it should have the 3.1.0
servlet API, so I don't think it's an issue of requiring 3.1.0 when something
earlier is installed.
In development we use felix HTTP (we use bndtools, and that's just what it
uses), and the requirement is satisfied by the Apache Felix Servlet API bundle.
But Karaf uses pax-web instead, and nothing seems to provide that capability as
far as I can tell (looking at output of bundle:headers in the console).
Naively adding a maven dependency on org.apache.felix.http.servlet-api give me
a different, earlier, error
Unable to build assembly: [wrap/0.0.0]
My bundle is built using bndtools, I'm afraid I don't know at the moment how
that manifest requirement comes about, haven't managed to follow the whole
chain through yet.
So my question is, within Karaf, where do I get this dependency satisfied?
Can I easily just substitute felix HTTP in place of pax-web on the basis that
that's what we use in production? If so how? Naively adding felix HTTP as
dependencies in my pom.xml just gives this "wrap/0.0.0" error, which means
nothing to me.
Thanks.
