SLF4 API not found when launching as Eclipse Application

[reuteran]

I am trying to launch a model server in my eclipse application. I've included the model server bundles in my target platform and made sure they all resolve. It seems that the javalin jar in org.eclipse.emfcloud.modelserver.lib cannot find the slf4 APIs. There are no package imports for them in org.eclipse.emfcloud.modelserver.lib and from what I can tell they also aren't in any of the other jars in that bundle. In the example given you are using maven to resolve the APIs, but I am using PDE.

Am I missing a step here? Shouldn't the APIs be imported by the lib bundle?
