Combine javascript files and their source maps

I am struggling with the combination of multiple javascript files and their source maps.

The problem is: I use Google Closure Compiler to obfuscate two javascript files A and B, with generated source maps A.map and B.map. Since I apply different compilation options on them, so compiling A and B into a single file does not work for me. Now, I want to combine A and B to AB, and also combine A.map and B.map into AB.map.

How should I do this? Any existing tools suitable for this purpose?

There are a number of packages out there that will do the job for example with the grunt-concat-sourcemap package for node you can do the following:

grunt.initConfig({
  concat_sourcemap: {
    options: {},
    target: {
      files: {
        'dest/out.js': ['src/a.js', 'src/b.js']
      }
    }
  }
})

this will concatenate the two specified source files(in order), and write the output to dest/out.js and dest/out.js.map

here are some links to packages for grunt, gulp and plain node:
