如何在使用Grunt时检测不同文件夹中相同的文件名

How to detect same file names in different folders while using Grunt?

我需要使用grunt编写一个concat脚本。这是我的样板：

___js
|____dist
| |____vents
| | |____carousel.js
| | |____compare.js
| | |____style.js
|____src
| |____events
| | |____carousel.js
| | |____compare.js
| | |____styles.js
| |____handlers
| | |____carousel.js
| | |____compare.js
| | |____style.js

我如何告诉concat任务，将具有相同名称的文件连接到events和handlers文件夹中，并将每个单独的连接对放在dist/vvents目录中？

我也遇到过类似的问题：如果在给定的路径模式中检测到具有相同文件名的文件，我希望我的构建失败。我已经通过编写自定义任务解决了这个问题。你可以使用grunt.file.expan或grunt.ffile.recurse GruntAPI

也许这会对你有所帮助（这是coffeescript而不是js）。

  grunt.registerMultiTask "noduplicates", "Detects duplicated filenames", () ->
    path = require('path')
    dupFilenamesCounted = {}
    haveDuplicates = false
    options =
      cwd: this.data.cwd
    grunt.file.expand(options, this.data.src).forEach (filepath) ->
      filepathParts = filepath.split(path.sep)
      filename = filepathParts.slice(-1).join(path.sep)
      unless dupFilenamesCounted[filename] is undefined
        dupFilenamesCounted[filename].counter++
        dupFilenamesCounted[filename].filepaths.push(filepath)
      else
        dupFilenamesCounted[filename] = { counter: 0, filepaths: [ filepath ] }
    for filename of dupFilenamesCounted
      if dupFilenamesCounted[filename].counter > 0
        grunt.log.error "Filename: " + filename + ' has ' + dupFilenamesCounted[filename].counter + ' duplicates: ' + dupFilenamesCounted[filename].filepaths
        haveDuplicates = true
    # Fail by returning false if this task had errors
    return false if haveDuplicates

然后你定义你的任务：

noduplicates:
  images:
    cwd: '<%= pkg.src %>'
    src: [ 'static/**/*.{gif,png,jpg,jpeg}' ]
