使用globlob模式时grunt-contrib-concat的奇怪行为

我正在使用grunt，我想按特定顺序在某个目录中合并所有js文件（这是一个有角度的js应用程序，因此我想先进行模块定义，然后再进行其他操作）。我的咕unt连音目标看起来像：

concat: {

    mobile: {
        expand: true,
        cwd: "static/javascript/mobile/app/",
        src: ["main-module.js", "**/*-module.js", "**/*.js", "!static/javascript/mobile/dist/*"],
        dest: "static/javascript/mobile/app/dist/ngmobile.concat.js"
    }
}

上面的配置似乎应该先连接main-module.js，再连接所有其他module.js文件，再连接其他所有文件，并忽略dist文件夹中的所有文件。但是，当使用--verbose运行grunt时，结果如下所示：

Running "concat:mobile" (concat) task

这告诉我，它正在查找要查找的文件，然后尝试将它们写入（复制？）到dest中指定的文件路径中。我怎么会这么严重地弄错呢？:)如果有人愿意把最后几根头发留在我的头上，我将非常感谢您提供有关我在这里做错了什么的信息。我想将src中的所有文件合并到dest文件中。

如果删除expand属性，则输出如下所示：

请注意，“文件：...”上方的第三行列出了我要查找的所有文件，但随后说未找到源文件。

Matt下面的解决方案解决了这个问题，下面是我的更新代码：

concat: {
    mobile: {
        dest: "static/javascript/mobile/app/dist/ngmobile-concat.js",
        src: (function () {
            var cwd = "static/javascript/mobile/app/";
            var files = ["*-module.js", "**/*-module.js", "**/*.js"];

            files = files.map(function (file) {
                return cwd + file;
            });

            files.push("! static/javascript/mobile/app/dist");

            return files;
        }())
    }
}

马修·巴卡蒂斯（Matthew Bakaitis）

我自己使用了棱角分明的应用程序遇到了这个问题，我考虑了以下三种选择：

1）按照项目github线程上的建议

你不是一个人。在grunt-contrib-concat github项目上有一个关于此问题的长篇文章。它与的工作方式cwd有关dest。

此处发布的建议解决方法将cwd属性移到一个函数中，该函数然后产生预期的结果，而不是ENOTDIR错误。

src: (function() {
  var cwd = 'src/js/';
  var arr = [];
  // determine file order here and concat to arr
  return arr.map(function(file) { return cwd + file; });
}())

我认为缺点是在gruntfile中增加了一个功能，这通常非常简单。如果您不是唯一维护该应用程序的人，这可能会造成混淆。

2）放弃cwd并使用带有<％=％>变量语法的静态方法

如果您的src和dest目录在整个gruntfile中是一致的，则可以这样定义src和dest目录：

myapp: {
  // configurable paths
  app: "static/javascript/mobile/app/",
  dist: "static/javascript/mobile/app/dist/"
}

...然后您可以删除该cwd属性，并将其配置为看起来更“静态”：

concat: {

    mobile: {
        expand: true,
        src: ["<%= myapp.app %>/main-module.js", "<%= myapp.app %>/**/*-module.js", "<%= myapp.app %>/**/*.js", "!<%= myapp.dist %>/*"],
        dest: "<%= myapp.dist %>/ngmobile.concat.js"
    }
}

对于我的大多数项目来说，这就足够了。当我稍后回来并需要进行更改时，它很简单，很干而且很容易理解。

授予：首先，由于所有<％=％>混乱，配置属性变得有点难以阅读，但是在我的编辑器中有一些格式可以改进。另外，另一位程序员阅读此书并了解您的意图非常容易。

3）使用类似usemin的插件为您完成此操作

如果您还在进行缩小，则可以考虑使用类似grunt-usemin的插件。

此选项的缺点是显而易见的：usemin增加了复杂性，因为你现在有另一个插件来管理和配置以及你需要格式化你的HTML使用usemin功能。起初，Usemin配置可能会造成混乱，如果您与团队合作，则修改usemin配置或usemin需求的HTML注释的程序员或设计人员很容易破坏事情。

好处是usemin将直接从HTML为您生成grunt的副本，concat和缩小配置。因此，如果您添加/删除脚本或更改HTML中的加载顺序，则无需在grunt配置中执行任何操作，因为usemin会选择它。
