Javascript 如何告诉Lineman将所有文件从/dist复制到其他目录？

当我运行lineman build时，它会在/dist目录中生成所有缩小的CSS和JS。我不知道如何让它将这些缩小的文件复制到另一个目录，即路径-../lib/app/Public处的公共目录

我的Lineman配置文件如下所示

# Exports an object that defines
#  all of the configuration needed by the projects'
#  depended-on grunt tasks.
#
# You can familiarize yourself with all of Lineman's defaults by checking out the parent file:
# https://github.com/testdouble/lineman/blob/master/config/application.coffee
#

module.exports = require(process.env['LINEMAN_MAIN']).config.extend('application', {
  removeTasks:
    common: [ "webfonts:dev", "images:dev"]
    dist: ["images:dist", "webfonts:dist", "pages:dist"]

  server:
    apiProxy:
      enabled: true
      host: 'localhost'
      port: 4567

  # enableSass: true

  # configure lineman to load additional angular related npm tasks
  loadNpmTasks: [ "grunt-ngmin"]

  # task override configuration
  prependTasks:
    dist: ["ngmin"]         # ngmin should run in dist only

  watch:
    scripts:
      files: ["generated/**"],
      tasks: ['copy:dev']

  copy:
    dev:
      files: [expand: true, cwd: 'generated', src: ['css/**', 'js/**', '!**/spec.js', 
              '!**/*.less*', '!**/*.coffee*', '!**/*.*.map'], dest: '../lib/app/public' ]

  # configuration for grunt-ngmin, this happens _after_ concat once, which is the ngmin ideal :)
  ngmin: {
    js: {
      src: "<%= files.js.concatenated %>",
      dest: "<%= files.js.concatenated %>"
    }
  },
})

我知道Lineman中有一个copy:dist default任务，但不确定它是如何工作的，无法从文档中正确理解它，在Lineman的帮助下，我解决了这个问题：

编写自定义任务tasks/dl-dev-copy.js来复制文件：

module.exports = function(grunt) {
   return grunt.registerTask('dl-dev-copy', 'Copy UI artifacts to wildfly deployment folder', ['copy:dl-dev-copy']);
};

更新了application.js文件关键部分很重要，我只有在线路员的帮助下才能弄明白：

loadNpmTasks: lineman.config.application.loadNpmTasks.concat('grunt-contrib-copy'),
   copy: {
      'dl-dev-copy': {
        files: [{
            expand: true,
            cwd: 'generated/',
            src: ['**'],
            dest: '../../../target/iq/'
        }]
    }
},
watch: {
    target: {
        "files": ["app/**/*", "spec/**/*", 'spec-e2e/**/*'],
        "tasks": 'dl-dev-copy'
    }
},
appendTasks: {
    common: ["dl-dev-copy"]
}

有关lineman run的输出，请参见下面的内容。在监视文件更改时，它与此类似，我们运行lineman build：

lineman run
Running "common" task
...       
 Running "copy:dl-dev-copy" (copy) task
Created 6 directories, copied 23 files
