RMDIR does not delete VM paths

[andre-ferreira-qlik]

Hello,

On the current version (1.0.0) i've obtained:

Running "clean:workFolder" (clean) task
ERROR
Warning: Unable to delete "/Volumes/C/Users/Andre/Documents/work/selection-list" file (EINVAL, rmdir '/Volumes/C/Users/Andre/Documents/work/selection-list'). Use --force to continue.

The force flag is present, here's the grunt task:

module.exports = function (grunt) {
'use strict';

grunt.loadNpmTasks('grunt-contrib-clean');
grunt.config('clean', {
options : {
force : true
},
workFolder : {
src : [
grunt.option('project').qlikVMExtensionPath + '/**',
grunt.option('project').qlikVMExtensionPath
]
}
....

Please advice, version ^0.6.0 didn't complain.
