使用Grunt.js副本将所有文件从目录复制到另一个目录 [英] Copy all files from directory to another with Grunt.js copy

问题描述

我试图将目录中的所有文件复制到另一个目录，作为我的构建过程的一部分。它适用于我明确指定的单个文件，但是当我尝试复制整个目录时，它会执行奇怪的操作，例如复制完整的目录结构（或根本没有任何内容）。以下是我的GruntFile.js中的相关部分：

 复制：{
 myvoice：{
 files ：[
 {src：src / html / index.html，dest：dist / myvoice / index.html}，
 {src：src / html / css / style.css ，dest：dist / myvoice / css / style.css}，
 {src：src / html / js / require.js，dest：dist / myvoice / js / require.js}， 
 {src：build / myvoice / main.js，dest：dist / myvoice / js / main.js}，
 {src：src / html / css / fonts / * ，dest：dist / myvoice / css / fonts /} 
] 
} 
}，
  

具体来说，这是我无法工作的最后一行：

  {src： src / html / css / fonts / *，dest：dist / myvoice / css / fonts /} 
  

>解决方案 ：true 选项，如这个答案可能适用于某些情况，但在我看来，更常见的要求（如我的情况）是将文件夹及其子文件夹结构原样复制到 dest 。看来在大多数情况下，如果你有子文件夹，他们可能在代码中被这样引用。执行此操作的关键是 cwd 选项，该选项将保留相对于指定工作目录的文件夹结构：

<$ p
files：{
cwd：'path / to / files'，//设置工作文件夹/ root复制
src：'* * / *'，//复制所有文件和子文件夹
dest：'dist / files'，//目标文件夹
展开：true //使用cwd时需要
}
}

I'm trying to copy all the files in a directory to another directory as part of my build process. It works fine for individual files that I specify explicitly but when I try to copy the whole directory it does weird things like copies the full directory structure (or nothing at all). Here is the relevant part from my GruntFile.js:

copy: {
  myvoice: {
    files: [
      { src:"src/html/index.html", dest:"dist/myvoice/index.html" },
      { src:"src/html/css/style.css", dest:"dist/myvoice/css/style.css" },
      { src:"src/html/js/require.js", dest:"dist/myvoice/js/require.js" },
      { src:"build/myvoice/main.js", dest:"dist/myvoice/js/main.js" },
      { src:"src/html/css/fonts/*", dest:"dist/myvoice/css/fonts/" }
    ]
  }
},

Specifically it's the last line that I can't get to work:

      { src:"src/html/css/fonts/*", dest:"dist/myvoice/css/fonts/" }

解决方案

The flatten: true option as in this answer might work for some cases, but it seems to me that the more common requirement (as in my case) is to copy a folder and its sub-folder structure, as-is, to dest. It seems that in most cases if you have sub-folders, they are probably being referenced that way in code. The key to doing this is the cwd option, which will preserve folder structure relative to the specified working directory:

copy: {
  files: {
    cwd: 'path/to/files',  // set working folder / root to copy
    src: '**/*',           // copy all files and subfolders
    dest: 'dist/files',    // destination folder
    expand: true           // required when using cwd
  }
}
