  nodemon({
        script:  '/server.js'
        , env: { 'NODE_ENV': 'development' }
        , ext: '*'
        , watch: [
            buildConfig.sharedFolder,
            'gulp-tasks'
        ]
        , tasks: function(changedFiles) {
            console.log('changed file is ' + changedFiles);
            return tasks
        }
        , delay: 2000
        , verbose: true
        , stdout: false

tasks: function (changedFiles) always receives a single file instead of an array of changed files.
