Grunt plugin for running Robocopy. NOTE: this plugin requires Grunt 0.4.x.

Getting Started

From the same directory as your project's Gruntfile and package.json, install this plugin with the following command:

$ npm install grunt-robocopy --save-dev

Next add this line to your project's Gruntfile:



    robocopy: {
        options: {
            //Global task options here. Merged with each target options
        bin: {
            options: {
                source: 'src/SomeProject.Web/bin',
                destination: 'build/bin',
                files: ['*.dll'],
        views: {
            options: {
                source: 'src/SomeProject.Web/Views',
                destination: 'build/Views',
                copy: {
                    subdirs: true,
                    multiThreaded: true


Inside your Gruntfile.js file, add a section named robocopy, for the robocopy options. The options below mirror those of the robocopy command itself, so check out the robocopy documentation for more details.

robocopy: {
    main: {
        options: {

            // Specifies the path to the source directory.
            source: '',

            // Specifies the path to the destination directory.
            destination: '',

            // Specifies the file or files to be copied. You can use wildcard characters (* or ?), if
            // you want. If the File parameter is not specified, *.* is used as the default value.
            files: ['*.html', '*.js', '/bin/*.*'],
