How can I copy to multiple destinations?

[F21]

Here's my current config:

copy: {
      build: {
        files: [
            //Copy the javascript files
            {
              expand: true,     // Enable dynamic expansion.
              cwd: 'scripts/',
              src: ['**/*.js'], // Actual pattern(s) to match.
              dest: '../js/',   // Destination path prefix.
              ext: '.js',   // Dest filepaths will have this extension.
              rename: function(dest, src){
                    return dest + src; //this is actually much more complicated in my code
              }
            },

            //Copy the javascript files -debug
            {
              expand: true,     // Enable dynamic expansion.
              cwd: '../js/',
              src: ['**/*.js'], // Actual pattern(s) to match.
              dest: '../js/',   // Destination path prefix.
              ext: '-debug.js',   // Dest filepaths will have this extension.
            },
        ],
      }
    }

What I want to do is this:

1. Drop into scripts folder and do some processing and renaming so that the result lives in ../js.
2. Go into ../js and go through each .js file and for each file, make an exact copy in the exact location with the filename ending in -debug.js.

With my current config, if I run grunt the first time, only the first task (drop into scripts and do the processing/copying)` would run.

I need to run grunt again in order for the second copy (debug) to be generated.

It seems to me that before performing any copy, it actually first check to see if all the copy rules can be executed even though the second copy rule depends on the first one.

Is there anyway to make grunt ignore that and just run the first then second rule sequentially?

This should be filed on Grunt. Opening an issue that references this over there.

Actually, if you just put the second set of files you want to copy in another target you'll be good to go.

Something like this:

copy: {
  build: {
    expand: true,
    cwd: 'scripts/',
    src: ['**/*.js'], 
    dest: '../js/',
    ext: '.js'
  },
  debug: {
    expand: true, 
    cwd: '../js/',
    src: ['**/*.js'], 
    dest: '../js/',   
    ext: '-debug.js',
  }
}
