私は最近an "older", 2009, article about how to make a Custom Rake tasksを読んでいます。これまでのところ、最初の反復で動作しますが、私はRake::TestTaskcan be called twiceを見ました。私はそれを行うことができると考えましたが、私のnameはattr_accessorが渡しているシンボルをピックアップしていません。Rake :: TestTaskと同じRakefileでカスタムRakeタスクを2回呼び出すことができません
require 'rake'
require 'rake/tasklib'
module Phil
class FooTask < Rake::TaskLib
attr_accessor :name
attr_accessor :data
attr_accessor :task_dependencies
def initialize(name = :task, task_dependencies)
@name = name
@data = nil
yield self if block_given?
@task_dependencies = task_dependencies
define
end
def define
desc "Run the #{@name} task"
task @name => @task_dependencies do
puts 'Some Test being Printed'
puts @data
sh 'echo blah'
end
self
end
end
end
Phil::FooTask.new :foo, [:call_me_first, :call_me_second]
task :call_me_first do
puts 'I am called first because I am a dependency'
end
task :call_me_second do
puts 'I am called second because Im also a dependency'
end
Phil::FooTask.new(:stuff) do |t|
t.data = 'I am a stuff task.'
end
以下は私が得た結果です。
C:\Users\user01\Desktop
λ rake --tasks
rake foo # Run the foo task
rake stuff # Run the stuff task
C:\Users\user01\Desktop
λ rake foo
I am called first because I am a dependency
I am called second because Im also a dependency
Some Test being Printed
echo blah
blah
C:\Users\user01\Desktop
λ rake stuff --trace
** Invoke stuff (first_time)
rake aborted!
Don't know how to build task '{}' (see --tasks)

Tasks: TOP => stuff
なぜレイクタスクが失敗しているのかわかりません。 Rake's TestTaskコードを読んでも、私はほとんど全てを正しく行っているようです。また、私はRubyの専門家ではなく、すべての小さなトリックだと言います。
