【问题描述】：

我在 Gruntfile 中使用 Grunt 复制任务。该项目由 Yeoman 创建。

我正在寻找有关如何简化任务定义的建议。您会注意到每组文件的 expand 和 dest 字段都是相同的。有没有办法可以简化这个？我可以使用选项吗？

这是我的任务

copy: {
  componentsToTmp: {
    files: [
      {
        expand: true,
        cwd: '<%= yeoman.components %>/angular',
        dest: '<%= yeoman.tmp %>/js',
        src: ['angular.min.js']
      },
      {
        expand: true,
        cwd: '<%= yeoman.components %>/angular-bootstrap',
        dest: '<%= yeoman.tmp %>/js',
        src: ['ui-bootstrap-tpls.min.js']
      },
      {
        expand: true,
        cwd: '<%= yeoman.components %>/angular-cookies',
        dest: '<%= yeoman.tmp %>/js',
        src: ['angular-cookies.min.js']
      },
      {
        expand: true,
        cwd: '<%= yeoman.components %>/angular-l10n/build',
        dest: '<%= yeoman.tmp %>/js',
        src: ['l10n.min.js']
      },
      {
        expand: true,

      },
      {
        expand: true,
        cwd: '<%= yeoman.components %>/bootstrap/bootstrap/js',
        dest: '<%= yeoman.tmp %>/js',
        src: ['bootstrap.min.js']

      {
        expand: true,

      {

        dest: '<%= yeoman.tmp %>/js',
        src: ['qrcode.min.js']
      },
      {

        cwd: '<%= yeoman.components %>/underscore',
        dest: '<%= yeoman.tmp %>/js',

这样的？

copy: {
  components: {
    files: [{
      src: [
        '<%= yeoman.app %>/angular-local-storage-obscure/angular-local-storage-obscure.js',
        '<%= yeoman.components %>/underscore/underscore-min.js',
        '<%= yeoman.components %>/qrcode/qrcode.min.js',
        '<%= yeoman.components %>/momentjs/min/moment.min.js',
        '<%= yeoman.components %>/jquery-ui/ui/minified/jquery-ui.min.js',
        '<%= yeoman.components %>/jquery/jquery.min.js',
        '<%= yeoman.components %>/bootstrap/bootstrap/js/bootstrap.min.js', // etc
      ],
      dest: '<%= yeoman.tmp %>/js',
      expand: true,
      flatten: true,
      filter: 'isFile'
    }]
  }
}
