Change reference to file in the sourcemap

[danyeah]

Hello Currently my autoprefixer task (im using grunt) takes in input "main.temp.css" which is generated by sass...and outputs "main.css" and "main.css.map" the issue is that since the sourcemap references "main.temp.css" it is useless because the filename is different from what devtools expects.

Is there any way i can change this behaviour? I've tried using the map options but with no luck.

        autoprefixer: {
            options: {
                browsers: [
                    'last 4 version',
                    'Firefox ESR',
                    'Opera 12.1',
                    '> 1%',
                    'ie 8',
                    'ie 7'
                ],
                map: {
                    prev: 'css/',
                    annotation: 'css/main.css.map',
                    //sourceContent: true
                },
            },
            dev: {
                src: '<%= ground.cssFileTemp %>',
                dest: '<%= ground.cssFileTemp %>'
            },
        },

autoprefixer: {
    options: {
        map: true
    },
    dev: {
        src: 'css/main.temp.css',
        dest: 'css/main.css' // -> main.css, main.css.map
    }
}
