[chef] Application Cookbook

[Haselwanter Edmund < >]

Hi *,

I want to leverage the application cookbook for installing multiple 
applications of the same type.
So I thought I re-use e.g. the application::java_webapp recipe. But this 
obviously (or *not* so obviously) 
does not work the way I thought it should.

Problem is:

search(:apps) do |app|
  (app["server_roles"] & node.run_list.roles).each do |app_role|

    app["type"][app_role].each do |thing|
      node.run_state[:current_app] = app
      include_recipe "application::#{thing}"
    end
  end
end   

Does the loop correctly, BUT include_recipe will only work for the first 
application of a type (which is by design)

application::java_webapp, because I have already seen it.
[Thu, 21 Apr 2011 01:15:22 -0700] DEBUG: I am not loading 
application::java_webapp, because I have already seen it.
[Thu, 21 Apr 2011 01:15:22 -0700] DEBUG: I am not loading 
application::java_webapp, because I have already seen it.

So what to do instead? 

1) Use a definition for DRY? But that is depricated, but somehow would feel 
correct? 
2) Use LWRP just to reuse the code from java_webapp. 
3) Patch chef itself to allow a "force_include"
4) just copy the code to distinct recipes. But that's not DRY

any thoughts?
