[wildfly-dev] Adding jar to WAR from DeploymentProcessor

[Stan Silvert]

The Keycloak auth server allows third-parties to add providers using the 
ServiceLoader.  To do this, you need to open Keycloak's auth-server.war 
and drop your jar into the WEB-INF/lib directory.

I'd like to eliminate opening the WAR and have a DeploymentProcessor 
look in a particular directory and add the jar at deployment time. What 
is the cleanest way to do that?

Bonus points if you tell me that I can treat the service provider jar as 
a deployment and let the user upload it via CLI. :-)

Thanks,

Stan
