Gulp acting differently on remote server - node.js

Question

I run the same gulpfile on local and remote. On local, everything is fine but when on remote, both "vendors" and "assets" tasks are not doing anything and there's no error when I run the gulp. Below is my gulp script -
var gulp = require('gulp'),
gutil = require('gulp-util'),
clean = require('gulp-clean'),
changed = require('gulp-changed'),
concat = require('gulp-concat'),
rename = require('gulp-rename'),
jshint = require('gulp-jshint'),
uglify = require('gulp-uglify'),
less = require('gulp-less'),
csso = require('gulp-csso'),
jade = require('gulp-jade'),
es = require('event-stream'),
embedlr = require('gulp-embedlr'),
refresh = require('gulp-livereload'),
express = require('express'),
http = require('http'),
lr = require('tiny-lr')();
gulp.task('clean', function () {
// Clear the destination folder
gulp.src('dist/**/*.*', { read: false })
.pipe(clean({ force: true }));
});
// Vendor Files
// var vendors = {
// js: [ './bower_components/**/ZeroClipBoard.js'],
// assets: ['./bower_components/**/ZeroClipBoard.swf']
// };
// Compile JS
gulp.task('scripts', function () {
return es.concat(
// Detect errors and potential problems in your JavaScript code
// You can enable or disable default JSHint options in the .jshintrc file
// Concatenate, minify and copy all JavaScript (except vendor scripts)
gulp.src(['./src/js/**/*.js'])
.pipe(concat('main.js'))
.pipe(uglify({mangle: false}))
.pipe(gulp.dest('./dist/js'))
.pipe(refresh(lr))
)});
// Copy Vendor Script and Assets
gulp.task('assets', function () {
return gulp.src(['./bower_components/**/ZeroClipBoard.swf'], {base: './'})
.pipe(gulp.dest('./dist/vendors'));
});
gulp.task('vendors', function () {
return gulp.src(['./bower_components/**/ZeroClipBoard.js'])
.pipe(concat('vendor.js'))
.pipe(uglify({mangle: false}))
.pipe(gulp.dest('./dist/js'));
});
// Compile LESS files
gulp.task('styles', function () {
return gulp.src('./src/less/styles.less')
.pipe(less())
.pipe(rename('styles.css'))
.pipe(csso())
.pipe(gulp.dest('./dist/css'))
.pipe(refresh(lr));
});
gulp.task('templates', function () {
// Compile Jade files
return gulp.src('./src/jade/index.jade')
.pipe(jade())
.pipe(rename('index.html'))
.pipe(gulp.dest('./dist/'))
.pipe(refresh(lr));
});
gulp.task('server', function () {
// Create a HTTP server for static files
var port = 3000;
var app = express();
var server = http.createServer(app);
app.use(express.static(__dirname + '/dist'));
server.on('listening', function () {
gutil.log('Listening on http://localhost:' + server.address().port);
});
server.on('error', function (err) {
if (err.code === 'EADDRINUSE') {
gutil.log('Address in use, retrying...');
setTimeout(function () {
server.listen(port);
}, 1000);
}
});
server.listen(port);
});
gulp.task('lr-server', function () {
// Create a LiveReload server
lr.listen(35729, function (err) {
if (err) {
gutil.log(err);
}
});
});
gulp.task('watch', function () {
// Watch .less files and run tasks if they change
gulp.watch('./src/less/**/*.less', ['styles']);
// Watch .jade files and run tasks if they change
gulp.watch('./src/jade/index.jade', ['templates']);
// Watch .js files
gulp.watch('./src/js/**/*.js', ['scripts']);
});
// The dist task (used to store all files that will go to the server)
gulp.task('dist', ['clean', 'styles', 'templates', 'scripts', 'vendors']);
// The default task (called when you run `gulp`)
gulp.task('default', ['clean', 'styles', 'templates', 'scripts', 'assets', 'vendors', 'lr-server', 'server', 'watch']);
