Cwd in Grunt + Babel

Question

Personal talk, I am using Grunt + Babel to compile my code, it turns out that my folders are organized as follows:

- pasta1
    - amd
        -src 
            - arquivo.js
- pasta2
     - amd
         -src 
            - arquivo.js
- pasta3
  -subpasta3
      - amd 
         - src
            -arquivo.js

And I can only use Abel in a very specific way, for example:

grunt.initConfig({
    babel: {
      options: {
        sourceMap: false,
        presets: ['env']
      },
      dist: {
        files: [{
          expand: true,
          cwd: './pasta1/amd/src', // aqui so especifico a pasta1
          src: ['*.js'],
          dest: '.pasta1/amd/babel/' // aqui so especifico a pasta1
        }]
      }
    }

I wanted it to run in all amd/src folders and generate inside the amd folder itself/ the files compiled by Babel, I’ve tried the following:

grunt.initConfig({
    babel: {
      options: {
        sourceMap: false,
        presets: ['env']
      },
      dist: {
        files: [{
          expand: true,
          cwd: '**/amd/src',  
          src: ['*.js'],
          dest: '**/amd/babel/' 
        }]
      }
    }

CWD: I don’t know why it doesn’t work, the idea was to take all the folders that contain the amd/src folders and make it the basis

DEST: in that part I have no idea how to leave the dest (Babel/ generated folder) exactly inside the folder that src is in, for example... inside paste1/src create the Babel/ folder with all files . js compiled from pasture 1, within pasture2/src create folder Babel/ with tds files. js compiled from pasture2
