dev和prod之间的Grunt切换任务

Question

I have a grunt file I am trying to see if I can split so I can call something like grunt build:dev or grunt build:prod .

Right now the task looks like this -

grunt.registerTask('build', "Building all needed files.", [
    'clean:build',
    'check-code',
    'clean:dist',
    'dist:prepare',
    'copy',
    'cssmin',
    'injector',
    'webpack:prod',
    'create-status-page'
]);

And I am wondering if there is a way to split this task like you can with configs with a key of dev and prod , where the task list for prod it slight different than dev. Sort of similiar to how you might do it with tha configs like

 return {
    dev: {
     ...
    },
    prod: {
     ...
    }  
 }

Is something like this possible? To be clear, I am asking if I can get away with registering both these in a single task.

You may be able to use a multitask .

grunt.initConfig({
  build: {
    dev:  ['task1', 'task2', 'task3'],
    prod: ['taskA', 'taskB', 'taskC']
  }
});

grunt.registerMultiTask('build', 'Building...', function() {
  grunt.task.run(this.data);
});

Then you can do grunt build:dev or grunt build:prod

Note: If you just do grunt build , it will iterate through all of the properties, so it would run both dev tasks and prod tasks.
