[chef] Re: Re: Re: Using Chef to install Java (my first recipe)

[Daniel DeLeo < >]

Usually, reasonable defaults will have been set for you (in 3rd party 
cookbooks) in an attributes file, usually attributes/default.rb  

Note that on chef-solo, you can cause yourself problems if you do the 
following:

1. add a cookbook to your cookbook_path
2. run a recipe from that cookbook with `include_recipe` without specifying 
the dependency in the including recipe’s metadata.rb

What happens in that case is, chef will directly include the recipe without 
having first loaded that cookbook’s supporting files (like the attributes 
files). This happens because chef uses the dependency information to 
determine the correct order to load cookbook’s non-recipe files, and a 
cookbook that isn’t reachable from the run_list or dependencies isn’t loaded 
at all.

So, assuming this is your issue, you can fix it by adding the java cookbook 
as a dependency of whatever cookbook you’re including it from.
