ruby - Got "undefined method `[]' for nil:NilClass" installing java Cookbook -

i try set vagrant vm using chef solo , berkshelf. want use maven cookbook. "maven" depends on "java" , "java_ark" (which included in "java" cookbook). of them created opscode.

but everytime error:

nomethoderror  -------------  undefined method `[]' nil:nilclass     cookbook trace: ---------------   /tmp/vagrant-chef-1/chef-solo-1/cookbooks/java/recipes/default.rb:21:in `from_file'   /tmp/vagrant-chef-1/chef-solo-1/cookbooks/platform-slayer/recipes/slayer_worker.rb:2:in `from_file'   relevant file content: ---------------------- /tmp/vagrant-chef-1/chef-solo-1/cookbooks/java/recipes/default.rb:   14:  # unless required applicable law or agreed in writing, software  15:  # distributed under license distributed on "as is" basis,  16:  # without warranties or conditions of kind, either express or implied.  17:  # see license specific language governing permissions ,  18:  # limitations under license.  19:  #  20:    21>> include_recipe "java::#{node['java']['install_flavor']}"  22:    23:  # purge deprecated sun java packages if remove_deprecated_packages true  24:  %w[sun-java6-jdk sun-java6-bin sun-java6-jre].each |pkg|  25:    package pkg  26:      action :purge  27:      only_if { node['java']['remove_deprecated_packages'] }  28:    end  29:  end  30: 

does know issue? let me know if need anymore information.

i think problem node['java'] evaluating nil.

one possible solution define attribute node['java']['install_flavor'] either in cookbook or in node definition or relevant role definition.

but looks bug in cookbook, because documentation says default should apply install_flavor attribute.
