将params传递给别名任务中的咕噜任务 [英] Pass params to an grunt task from an alias task

问题描述

有没有办法将这样一个别名任务的参数传递给调用任务：

Is there a way to pass an argument from a alias task like this into on of the calling tasks:

grunt.registerTask('taskA', ['taskB', 'taskC'])

grunt taskA:test

，因此任务 taskB 和 taskC 将被调用参数 test ？

so that task taskB and taskC will be called with the parameter test?

推荐答案

您可以像这样创建动态别名任务：

You can create a dynamic alias task like this:

grunt.registerTask('taskA', function(target) {
  var tasks = ['taskB', 'taskC'];
  if (target == null) {
    grunt.warn('taskA target must be specified, like taskA:001.');
  }
  grunt.task.run.apply(grunt.task, tasks.map(function(task) {
    return task + ':' + target;
  }));
});
