[solved] Grunt Task problem, cssmin runs manually but not with "watch"

[horst]

Hey all,

I have setup a local dev workflow that used postcss (grunt-postcss) with the cssnano processor for finally minifying the css. But this broke a part of my css. So I switched to cssmin (grunt-contrib-cssmin). This does not brake my css when minifying but it get not invoked when the tasks get started through grunt watch. When I manually call grunt, all gets processed. I post my files below. Does anybody have an idea what I'm doing wrong?

Gruntfile.js

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

Working until late night isn't always productive. ?

        watch: {
            options: {
                //event: ['added', 'changed', 'deleted'],  // 'all'
                livereload: true,
                spawn: false
            },
            styles: {
                files: ['localdev/styles/**/*.scss'],
                tasks: ['sass', 'postcss'], // , 'cssmin'],       
                                            // ^^ while temporary switching between cssnano an cssmin, I finally forgot to register cssmin in "watch"
                options: {
                    event: ['added', 'changed', 'deleted']
                }
            },

So everything makes sense again. ?
