如何在Grunt Build中使用多个复制命令？

Question

I would like to copy some files, run other tasks, and then again copy some files:

copy:{....},
concat:{...},
copy:{...}

However, I get the following error when I run my grunt build:

SyntaxError: Duplicate data property in object literal not allowed in strict mode

Of course I understand, that I cannot use the same property (ie "copy") multiple times in the grunt json. But what is the solution to my problem? How can I copy at different positions of the gruntfile.js?

Many thanks!

Answer 1

Just split your copy comment in the desired subtasks:

copy: {
    task1: {
        files: [...]
    }
    task2: {
        files: [...]
    },
    task3: {
        files: [...]
    }
}

And then run Grunt like that:

grunt.registerTask('development', [ 'copy:task1', 'concat', 'copy:task2' ]);

Answer 2

I do the same job like this. Here is my task, right at the end of the Gruntfile:

grunt.registerTask('client', [
    'concat:app_js',
    'concat:lib_js',
    'uglify:app_lib_js',
    'concat:client_js',
    'concat:client_css',
    'includes',
    'concat:client_html',
    'copy:client_gfx',
    'copy:client_xml'
]);

This is referencing a structure higher up that looks like:

module.exports = function(grunt) {

grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),

    concat: { ... concat jobs here ... },

    // This is how to have multiple copy jobs
    copy: {
        client_gfx: {
            // spec here
        },
        client_xml: {
            // spec here
        }
    }
}
}
