for some reason the assembly generation loop is going one more time than expected

assembly_info_error.txt

FIXED thanks to quick look by Derick Bailey @derickbailey.  generate_assemblyinfo task needed to be a rake task and not assemblyinfo task.  easy fix.

### versions.yml
files:
  - OneAssemblyInfo: 1.0.0
  - TwoAssemblyInfo: 2.0.0
  - ThreeAssemblyInfo: 3.0.0
  - FourAssemblyInfo: 4.0.0
  - FiveAssemblyInfo: 5.0.0

### Rakefile
require 'rubygems'
require 'albacore'
require 'yaml'

desc "Generate the SharedAssemblyInfo file"
task :generate_assemblyinfo, :git_sha do |asm, args|
  git_sha = args[:git_sha] || "GIT SHA"
  raw_config = File.read('versions.yml')
  files = YAML.load(raw_config)['files']
  files.each do |file|
    file.keys.each do |key|
      version_prefix = file[key]
      output_file_path = key
      Rake::Task[:assemblyinfo].execute({ :git_sha => git_sha , :version_prefix => version_prefix , :output_file_path => output_file_path })
      # same output with .invoke
      # Rake::Task[:assemblyinfo].reenable
      # Rake::Task[:assemblyinfo].invoke(git_sha , version_prefix, output_file_path)
    end
  end
end

desc "Create the SharedAssemblyInfo file"
assemblyinfo :assemblyinfo, :git_sha, :version_prefix, :output_file_path do |asm, args|
  git_sha = args[:git_sha]
  version_prefix = args[:version_prefix]
  output_file_path = args[:output_file_path]
  product_name = output_file_path.gsub('AssemblyInfo','').split(/(?=[A-Z])/).map{|w| w.capitalize}.join(' ')
  build_number = ENV['BUILD_NUMBER']  #provided by teamcity

  copyright = "Copyright (c) 2001-#{Time.now.year}, Company, Inc. and/or its affiliates. All rights reserved."
  asm.version = "#{version_prefix}.#{build_number || 0}"
  asm.company_name = 'Company'
  asm.product_name = "Company #{product_name} Product"
  asm.description = git_sha
  asm.copyright = copyright
  asm.trademark = copyright
  asm.output_file = "#{output_file_path}.cs"
end
