[Grunt] Multitask, this.target, this.data, registerMultiTask()

When a multi task is run, Grunt looks for a property of the same name in the Grunt configuration. Multi-tasks can have multiple configurations, defined using arbitrarily named "targets."

grunt.registerMultiTask(taskName, [description, ] taskFunction)

module.exports = function(grunt){
    grunt.initConfig({
        tasks:{
            one: "first",
            two: "second",
            three:"third"
        }
    })

    grunt.registerMultiTask("tasks",function(){

        grunt.log.writeln(this.target+ ", "+ this.data)
    })
}

 

In cmd, you can type:

grunt tasks: three
grunt tasks
