Grunt cssmin rebasing a relative URI?

Question

I\'m currently setting up grunt-usemin for our project but I\'m running in a small issue with the cssmin task.

Our project depends on a few external lib

Answer 1

I have a grunt file in C:\web\project and CSS files in C:\web\project\www\css. The following snippet is from my grunt file and it rebases URLs correctly for me.

var cssFiles = [
      'www/css/layout/Header.css',
      'www/css/layout/Footer.css',
      'www/css/vendor/chosen/chosen.css'
      // ...
];

cssmin: {
        concat: {
                options: {
                        keepBreaks: true, //  whether to keep line breaks (default is false)
                        debug: true, // set to true to get minification statistics under 'stats' property (see test/custom-test.js for examples)
                        noAdvanced: true, // set to true to disable advanced optimizations - selector & property merging, reduction, etc.
                        //relativeTo: 'http://online-domain-tools.com/'
                        noRebase: false, // whether to skip URLs rebasing
                        root: 'www'
                },
                nonull: true,
                src: cssFiles,
                dest: 'www/temp/application.css'
        },
        minify: {
                options: {},
                nonull: true,
                src: ['www/temp/application.css'],
                dest: 'www/temp/application.min.css'
        }
},

// ...

grunt.registerTask('default', ['cssmin:concat', 'cssmin:minify']);

Can you post your gruntfile to compare it?
