[chef] Re: Re: The Application Cookbook Pattern vs. String / Node Attribute Interpolation in Attributes files

[Torben Knerr < >]

I also played around with `include_attribute` in the recipe, in the attributes file etc. but couldn't make it work. I also tried renaming my application cookbook and attribute files so that they come alphabetically before "java", but that didn't make any difference too (surely because of the `include_recipe "java"`).

I'm looking forward to the workaround mentioned by Noah, couldn't find it via Google so far. 

Btw: have you considered forking and "fixing" the Java cookbook rather than duplicating the attributes logic?

I just copy-pasta'd the java.java_home and java.openjdk_packages logic for a pr to the nexus cookbook: https://github.com/RiotGames/nexus-cookbook/pull/43

I attempted a well timed `include_attribute 'java'`, but couldn't make it work.

If there is a less terrible way, I'd love to know.
