Multiple watch configurations?

[kristianmandrup]

Trying to set up different watch configurations for dev vs prod
What am I missing?

 Verifying property watch.dev.files exists in config...ERROR
    >> Unable to process task.
    Warning: Required config property "watch.dev.files" missing.

        concurrent: {
            dev: {
                tasks: ['nodemon', 'watch:dev'],
                options: {
                    logConcurrentOutput: true
                }
            },
            prod: {
                tasks: ['nodemon', 'watch:prod'],
                options: {
                    logConcurrentOutput: true
                }
            }
        },

This is too many levels deep.

watch: {
  prod: {
    js: {

Can you prefix your watch tasks with 'prod_' or 'dev_', then call them like so:

tasks: ['nodemon', 'watch:dev_js', 'watch:dev_sass']

[aaronjpitts]

tasks: ['nodemon', 'watch:dev_js', 'watch:dev_sass'] doesn't work, it will only run the first watch task (watch:dev_js in this case)

Hey i had the same issue and did the same logic as you but that didn't work.
The working solution and working like a charm is this one: https://stackoverflow.com/questions/13833196/gruntjs-watch-different-folders-and-execute-tasks
Hope this helps. you need to install the grunt plugin: https://www.npmjs.com/package/grunt-focus
then add like you tried with concurrent: this code

focus: {
develop: {
include: ['dev']
},
master: {
include: ['prod']
},
},

and make ure tasks like this:

grunt.registerTask('dev', 'compile develop', ['focus:develop']);
grunt.registerTask('prod', 'compile production', ['focus:master']);
