用 grunt 任务同时看咖啡和玉文件

Question

我想同时看我的咖啡和咕噜声文件。当我只看咖啡文件时没有问题，但是当我在我的文件中添加一个玉观察者时，观察者只编译一次，即使有更新，观察者也不会编译那些新的更新。

感谢您的帮助：

这是我的系统中只有咖啡观察者的时候：

每当咖啡文件有更新时编译：Gruntfile.coffee

module.exports = (grunt) ->

  grunt.initConfig
    pkg         : grunt.file.readJSON "package.json"

    coffee      :
      compile   :
        options : sourceMap: on
        files   :
          ['dist/client/js/main.js': 'client/app/scripts/app.coffee',
          'server.js': 'server.coffee']

    watch       :
      coffee    :
        options : atBegin: yes
        files   : [ 'client/scripts/*.coffee',
                    'client/scripts/controllers/*.coffee',
                    'server.coffee']
        tasks   : ['coffee', 'jade']


  grunt.loadNpmTasks 'grunt-contrib-coffee'
  grunt.loadNpmTasks 'grunt-contrib-watch'

  grunt.registerTask 'default', ['watch']

问题是，为什么观察者只在启动时起作用而不再起作用？

仅在启动时编译：Gruntfile.coffee

module.exports = (grunt) ->

  grunt.initConfig
    pkg         : grunt.file.readJSON "package.json"

    coffee      :
      compile   :
        options : sourceMap: on
        files   :
          ['dist/client/js/main.js': 'client/app/scripts/app.coffee',
          'server.js': 'server.coffee']

    jade: 
      compile: 
        options: 
          data: 
            debug: false
        files: 
          ['dist/client/index.html': ['client/app/views/index.jade'] ]

    watch       :
      coffee    :
        options : atBegin: yes
        files   : [ 'client/scripts/*.coffee',
                    'client/scripts/controllers/*.coffee',
                    'server.coffee']
        tasks   : ['coffee', 'jade']


  grunt.loadNpmTasks 'grunt-contrib-coffee'
  grunt.loadNpmTasks 'grunt-contrib-jade'
  grunt.loadNpmTasks 'grunt-contrib-watch'


  grunt.registerTask 'default', ['watch']

这是我的控制台注销命令：grunt --verbose

您告诉watch 关注coffee 和jade 的变化，但只在files 数组中包含coffee 文件，我认为您还需要在其中添加jade 文件以进行观看

watch       :
  coffee    :
    options : atBegin: yes
    files   : [ 'client/scripts/*.coffee',
                'client/scripts/controllers/*.coffee',
                'server.coffee', 'client/app/views/index.jade'] // add the jade file here
    tasks   : ['coffee', 'jade']

更新

watch:
  coffee:
    files: ["client/scripts/*.coffee", "client/scripts/controllers/*.coffee", "server.coffee", "client/app/views/index.jade"]
    tasks: ["coffee"]

  jade:
    files: ["client/app/views/index.jade"]
    tasks: ["jade"]
