我如何从一个咕task任务中运行一个咕噜任务？ [英] How can I run a grunt task from within a grunt task?

问题描述

我创建了一个新的grunt任务，在其中我想使用grunt-contrib-concat将几个文件连接在一起。

我浏览了文档，但没有发现任何暗示能够做到的事情。这似乎是一个微不足道的用例，所以我可能只是在看一些东西。

更新1：

我也希望能够在我的自定义任务中配置此任务。 / p>

例如，我在自定义任务中创建了一个文件列表。在获得该列表后，我想将它们传递给concat任务。我该怎么做？

我希望能够做到这样的事情。

  grunt.task.run（'concat'，{src：['file1'，'file2']，dest：'out.js'}）
  
 
 
 
更新2：
 
 
 
为了实现我想要的，我必须手动配置grunt任务。这里有一个例子显示了我想要的东西。

解决方案
以下是在任务中手动配置任务并运行它的示例。

  grunt.registerMultiTask（'multicss'， '在文件夹中缩小CSS文件'，function（）{
 var count = 0; 
 grunt.file.expandFiles（this.data）.forEach（function（file）{
 var property ='mincss.css'+ count +'。files'; 
 var value = {}; 
 value [file] = file; 
 grunt.config（property，value）; 
 grunt.log.writeln（Minifying CSS+文件）; 
 count ++; 
}）; 
 grunt.task.run（'mincss'）; 
}）; 
  
 
I've created a new grunt task and within it I want to use grunt-contrib-concat to concatenate a few files together.  


I looked through the docs but I don't find anything that hinted at being able to do this.  It seems like a trivial use case, so I'm probably just over looking something.    

Update 1:

I also want to be able to configure this task from within my custom task.

For example, I create a list of files in my custom task. After I have that list, I want to pass them to the concat task.  How can I do that?

I would like to be able to do something like this.
grunt.task.run('concat', { src: ['file1','file2'], dest: 'out.js'})
Update 2:

To achieve what I want, I have to manually configure the grunt task.  Here's an example that showed me what I wanted.

解决方案
Here's an example of manually configuring a task within a task and then running it. 

https://github.com/gruntjs/grunt-contrib/issues/118#issuecomment-8482130
 grunt.registerMultiTask('multicss', 'Minify CSS files in a folder', function() {
        var count = 0;
        grunt.file.expandFiles(this.data).forEach(function(file) {
            var property = 'mincss.css'+count+'.files';
            var value = {};
            value[file] = file;
            grunt.config(property, value);
            grunt.log.writeln("Minifying CSS "+file);
            count++;
        });
        grunt.task.run('mincss');
    });
