How to ignore files grunt uglify
提问by Jamie Hutber
Background
背景
I've just started using grunt as of about 30mins ago. So bear with me.
大约 30 分钟前，我刚刚开始使用 grunt。所以请耐心等待。
But I have a rather simple script going that will look at my js and then compress it all into one file for me.
但是我有一个相当简单的脚本，它会查看我的 js，然后将其全部压缩到一个文件中。
Code
代码
"use strict";
module.exports = function (grunt) {
// load all grunt tasks
require('matchdep').filterDev('grunt-*').forEach(grunt.loadNpmTasks);
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
uglify: {
options: {
beautify: true,
report: 'gzip'
},
build: {
src: ['docroot/js/*.js', 'docroot/components/pages/*.js', 'docroot/components/plugins/*.js'],
dest: 'docroot/js/main.min.js'
}
},
watch: {
options: {
dateFormat: function(time) {
grunt.log.writeln('The watch finished in ' + time + 'ms at' + (new Date()).toString());
grunt.log.writeln('Waiting for more changes...');
}
},
js: {
files: '<%= uglify.build.src %>',
tasks: ['uglify']
}
}
});
grunt.registerTask('default', 'watch');
}
Question
题
My main.min.js is getting included in the compile each time. Meaning my min.js is getting 2x, 4x, 8x, 16x etc etc. Is best way around this is to add an exception and ignore main.min.js?
我的 main.min.js 每次都包含在编译中。这意味着我的 min.js 得到了 2x、4x、8x、16x 等。最好的方法是添加一个异常并忽略main.min.js？

To the endof the src array, add
在 src 数组的末尾，添加
'!docroot/js/main.min.js'
This will exclude it. The ! turns it into an exclude.
这将排除它。这 ！把它变成一个排除。

http://gruntjs.com/api/grunt.file#grunt.file.expand
Paths matching patterns that begin with ! will be excluded from the returned array. Patterns are processed in order, so inclusion and exclusion order is significant.
匹配以 ! 开头的模式的路径 将从返回的数组中排除。模式按顺序处理，因此包含和排除顺序很重要。
This is not specific to grunt uglify, but any task that uses grunt convention for specifying files will work this way.
这不是 grunt uglify 特有的，但任何使用 grunt 约定指定文件的任务都可以这样工作。
As a general advice though I would suggest putting built files somewhere else than your source files. Like in a root distfolder.
作为一般建议，我建议将构建的文件放在源文件之外的其他地方。就像在根dist文件夹中一样。
