Gather Options Before Execution Instead of During initConfig() (Enhancement)

Gather Options Before Execution Instead of During initConfig().
It would be very helpful if I could do this:

module.exports = function(grunt) {
  grunt.loadNpmTasks('grunt-shell');
  grunt.loadNpmTasks('grunt-debian-package');

  grunt.initConfig({
    shell: {
      get_version: {
        command: 'git describe',
        options: {
          stdout: false,
          callback: function(err, stdout, stderr, callback) {
            if (stdout.length !== 0) {
              grunt.option('version', stdout);
            } else {
              // fallback to the version in packge.json
              var package_json = grunt.file.readJSON('package.json');
              grunt.option('version', package_json.version);
            }
            callback();
          },
        },
      },
    },
    debian_package: {
      dist: {
        options: {
          version: grunt.option('version'),
          dependencies: '',
          maintainer: {
            name: 'JD',
            email: 'JD@example.com'
          },
        },
      },
    },
  });

  grunt.registerTask('package',[
    'shell:get_version',
    'debian_package:dist',
  ]);
}

Looking at the code you might even expect it to work. The problem is debian_package values are determined during grunt.initConfig(), so there's no opportunity to load values dynamically. When grunt.option('version') is called, shell:get_version has not yet run, so the value is undefined:

$ grunt package
Running "shell:get_version" (shell) task

Running "debian_package:dist" (debian_package) task
Warning: Cannot call method 'replaceAll' of undefined Use --force to continue.

I think this can be solved by making debian_package accept a function rather than an object during initConfig(). Something like this:

debian_package: {
  dist: function() {
    return {
      options: {
        version: grunt.option('version'),
        dependencies: '',
        maintainer: {
          name: 'JD',
          email: 'JD@example.com'
        },
      },
    };
  },
},

I was very excited to use grunt-debian-package, but until this is possible I cannot use it. If it is already possible somehow then I wasn't able to figure out how.

I have the same issue, any updates?

Not that I'm aware of. I had to abandon grunt-debian-package and go back to using a bash script.
