gruntjs - 指定cwd选项时，grunt-contrib-copy任务失败

Question

我有这个grunt-copy设置:

copy: {
        images: {
            cwd: 'src/multiselect/lib/',
            src: 'chosen.css',
            dest: './built/css/',
            flatten: true,
            filter: 'isFile'
        }
    },

当我运行它时，它总是会:

Running "copy:images" (copy) task
Warning: Unable to read "chosen.css" file (Error code: ENOENT). Use --force to continue.
Aborted due to warnings.

奇怪的是，如果我使用此配置运行它:

copy: {
        images: {
            src: 'src/multiselect/lib/chosen.css',
    //      src: 'chosen.css',
            dest: './built/css/',
            flatten: true,
            filter: 'isFile'
        }
    },

它每次都有效。有谁知道为什么吗？似乎在此代码行上发生了错误:

grunt.file.copy(src, dest, copyOptions); 

在grunt-contrib-copy任务中。任何帮助将不胜感激。

您需要添加expand:true
