Corrupted copy using grunt-contrib-copy

Question

I have an issue when copy a lot of files (images, pdf, etc) from one directory to another one. In a destination folder all these files is corrupted. I tried to use both noProcess and processContentExclude options but it brought no results.

My copy task config looks like this:

copy: {
  assets_images: {
    options: {
      noProcess: ['**/*.{png,gif,jpg,ico,pdf}']
    },
    expand: true,
    cwd: 'static/images/',
    src: '**',
    dest: 'dist/assets/images/'
  },
  assets_data: {
    options: {
      noProcess: ['**/*.{png,gif,jpg,ico,pdf}']
    },
    expand: true,
    cwd: 'static/data/',
    src: '**',
    dest: 'dist/assets/data/'
  }
}

Could you please help me with this?

UPDATE:

I did some investigations and found out that binary code of the png files in the source and destionation folders are differ.

I suspect that copy task process files using wrong encoding (by default it is utf8). As I understand it process them as a binary files and utf8 is not a correct encoding in this case.

What would you recomend to do for fix this issue?

What are you trying to do? Exclude files with these extensions? Does this make any sense: https://github.com/gruntjs/grunt-contrib-copy/issues/141#issuecomment-35052411? — meilke, Feb 16 '15 at 18:30
Since the files was corrupted after copying I added noProcess to the options to skip processing of these files. So I expect the files will be successfuly copied without modification and will not be corrupted. Is it a correct approach? And why the files is still corrupted after copying? — Volodymyr Machula, Feb 16 '15 at 21:20

In case you have a process function

The option name is processContentExclude, unless you're using version 0.5.0 or above, where it changed to noProcess according to https://github.com/gruntjs/grunt-contrib-copy#release-history

You can check your version with:

npm ls grunt-contrib-copy

Large copy config example from grunt-vtex:

copy:
      main:
        files: [
          expand: true
          cwd: 'src/'
          src: ['**'].concat(options.copyIgnore)
          dest: "build/<%= relativePath %>/"
        ]
      deploy:
        files: [
          expand: true
          cwd: "build/<%= relativePath %>/"
          src: ['**']
          dest: "#{pkg.deploy}/#{pkg.version}"
        ]
        options:
          processContentExclude: ['**/*.{png,gif,jpg,ico,psd,ttf,otf,woff,svg}']
          process: (src, srcpath) ->
            replaceFiles = grunt.config('deployReplaceFiles') ? grunt.config('deployReplaceFiles', glob.sync(options.replaceGlob))
            for file in replaceFiles when file.indexOf(srcpath) >= 0
              log "Replacing file...", file
              for k, v of options.replaceMap
                log "Replacing key", k, "with value", v
                src = src.replace(new RegExp(k, 'g'), v)
            return src

In case you don't have a process function

noProcess won't help if you don't have a process function.

If so, you should look at encoding option. https://github.com/gruntjs/grunt-contrib-copy#encoding

Maybe try encoding: null, as suggested here: https://github.com/gruntjs/grunt-contrib-copy/issues/64

Either way

Try and reproduce your problem in a minimal fashion - create a Gruntfile with only one task, copying only one image. This is not a common problem and maybe some other task is the culprit here.
