The tasks in my grunt file are running without errors but the files i'm asking it to create aren't being compiled. They are created if I simple run 'grunt' but if I use 'grunt watch' and save a file it doesn't update.
Particularly I am working on file 'script/src/latestNews.js' so on save this should concat with others to create 'script/dist/main.js', which it does. But it does not then go on to create 'dist/build.min.js' like it should.
module.exports = function (grunt) {
// Project configuration.

It looks like the array of tasks that are run by your watch:js task is simply missing a couple of critical tasks. Specifically you are not running the concat:build and uglify:build tasks.
Your current array of tasks:
['concat:srcJS', 'uglify:target', 'jshint:main', 'copy:js']
Complete/fixed array of tasks:
['concat:srcJS', 'uglify:target', 'jshint:main', 'concat:build', 'uglify:build', 'copy:js']
Replacing your current array with the fix that I supplied should solve your issue.
