JAX-RS deployments need to import more dependencies, specifically:

Jackson and HC4 are often used within jax-rs deployments because users
need to add additional configuration and initialization that can only be
done programmatically.

Part of the reason why we don't re-export third party libs we use is because we want the flexibility to upgrade/drop/replace, and we don't want to support a user using say google collections, just because we made use of it in our code base.

Yes, we have to expose and support direct usage. They are both
intricate in developing JAX-RS applications. Resteasy client framework
is just a layer on top of Apache HC. For example, we rely on HC4 APIs
to set up user/password and other authentication settings. Jackson
annotations are used a lot as well as creating
ObjectMapper's(JAXBContext equivalent) directly that are plugged in
through JAX-RS apis (ContextResolver).
I want to really apologize for not checking up on this months and months
ago. I incorrectly assumed that things would just work and be exposed
as they were in AS6. A lot of this is related to my lack of
understanding of the module system too.
</pre><blockquote type="cite"><blockquote type="cite"><pre wrap="">Another thing:
Can modules be declared with empty <resources>? It would be cool if we
could have a resteasy module with which all it did was define what
modules it would export to a deployment. Right now this metadata is
hardcoded, correct? This sucks for multiple reasons. One: users will
have to manually define a lot of module dependencies, or they will end
up including resteasy and thirdparty libraries that may conflict and
cause CCEs. Two: Its very hard for me to provide a patch to AS7 if I
want to provide *ALL* features that come with the resteasy distribution.
Sure I could include and export everything within the current resteasy
default module, but I would rather have separate modules for these features.
</pre></blockquote><pre wrap="">Sure we do that for javaee for example (aggregation modules). If you would like to make an aggregate for JAX-RS thats fine, the only problem is you will prevent people from being able to exclude anything in that list. So to use an example if you add apache http client 4.1, and a user decides they want 3.0 or 5.0, they would have to exclude the aggregate module, and then include everything in it except http client. You could also do various different common combinations.
</pre></blockquote><pre wrap=""><!---->
I just don't see a way around it. Couldn't they also just modify the
aggregation module? Maybe you need to add a feature to JBoss Modules
that allows a deployment to override the version of an exported dependency?</pre></div>
</blockquote>
<br>
If these are just added to the deployment as dependencies via the
JaxrsDependencyProcessor then they can be excluded and overridden by an
entry in jboss-deployment-structure.xml. If you make one big aggregation
module you loose that flexibility. <br>
<br>
I'm not saying that this is necessarily a massive problem, but that is
the price you pay for using an aggregation module. <br>
<br>
Something else we could potentially look at supporting is container
integration for bundled Resteasy, so if you include the Resteasy jars in
your application the scanning + EE integration code will still run, but
it will not add dependencies on the containers Resteasy jars. <br>

What do you think is better and would create less headaches for users?
An aggregate module? Or just ship with core resteasy? I think we may
be stuck with an aggregate module as the alternative would break
backward compatibility?
