我遇到过类似的问题: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来解决它。你可以使用 grunt.file.expand 或 grunt.file.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}' ]
