Gulp watch causes infinite build loop

my gulp watch keeps on a rebuild after saving js file, the Scss file working well, the problem is when saving other files inside the project folder, changing or replacing images, triggers the rebuild to start and finish building dist folder.
only while saving Scss files, the build starts and finishes as accepted.
terminal output:
[17:53:11] Starting 'js-build'...
[17:53:11] Finished 'js-build' after 452 ms
[17:53:11] Starting 'js-build'...
[17:53:12] Finished 'js-build' after 614 ms
[17:53:12] Starting 'js-build'...
please advice?

Gulp build task CSS paths and JS compilation

So I have the following basic project structure that I use throughout all my projects:
Where the src folder looks like this:
I use Pug(Jade), sass compiling and useref js compilation.
This is my Jade views structure:
And this is my Jade index file:
This is my Jade scripts file, that is included in the index:
This is my pre-build index file, which is constructed by the index.pug:
And this is the build version of the index file:
My Gulpfile looks like this:
var gulp = require('gulp'),
sass = require('gulp-sass'),
plumber = require('gulp-plumber'),
changed = require('gulp-changed'),
gutil = require('gulp-util'),
pug = require('gulp-pug'),
concat = require('gulp-concat'),
browserSync = require('browser-sync').create(),
useref = require('gulp-useref'),
uglify = require('gulp-uglify'),
gulpIf = require('gulp-if'),
cssnano = require('gulp-cssnano'),
imagemin = require('gulp-imagemin'),
cache = require('gulp-cache'),
del = require('del'),
cssAdjustUrlPath = require('gulp-css-adjust-url-path'),
runSequence = require('run-sequence');
function handleError(err) {
gutil.beep();
console.log(err.toString());
this.emit('end');
}
gulp.task('sass', function () {
return gulp.src('src/scss/**/*.scss')
.pipe(plumber({
errorHandler: handleError
}))
.pipe(sass()) // Using gulp-sass
.pipe(gulp.dest('src/css'))
.pipe(browserSync.reload({
stream: true
}));
});
gulp.task('sass-dist', function () {
return gulp.src('src/scss/**/*.scss')
.pipe(cssAdjustUrlPath(/(url\(['"]?)[/]?(assets)/g))
.pipe(sass()) // Using gulp-sass
.pipe(gulp.dest('dist/css'))
});
gulp.task('views', function buildHTML() {
return gulp.src('src/views/*.pug')
.pipe(changed('src', {
extension: '.html'
}))
.pipe(pug({
pretty: true
}))
.pipe(gulp.dest('src/'))
});
gulp.task('views-dist', function buildHTML() {
return gulp.src('src/views/*.pug')
.pipe(changed('src', {
extension: '.html'
}))
.pipe(pug({
pretty: true
}))
.pipe(gulp.dest('dist/'))
});
gulp.task('watch', ['browserSync', 'views', 'sass'], function () {
gulp.watch('src/scss/**/*.scss', ['sass']);
gulp.watch('src/views/**/*.pug', ['views']);
// Reloads the browser whenever HTML or JS files change
gulp.watch('src/js/**/*.js', browserSync.reload);
gulp.watch('src/*.html', browserSync.reload);
});
gulp.task('browserSync', function () {
browserSync.init({
server: {
baseDir: 'src'
},
port: 3000
});
});
gulp.task('useref', function () {
return gulp.src('src/*.html')
.pipe(useref())
.pipe(gulpIf('*.js', uglify()))
// Minifies only if it's a CSS file
.pipe(gulpIf('*.css', cssnano()))
.pipe(gulp.dest('dist'));
});
gulp.task('useref-dist', function () {
return gulp.src('src/**/*.html')
.pipe(useref())
.pipe(gulpIf('*.js', uglify()))
// Minifies only if it's a CSS file
.pipe(gulpIf('*.css', cssnano()))
.pipe(gulp.dest('dist'));
});
gulp.task('images', function () {
return gulp.src('src/images/**/*.+(png|jpg|jpeg|gif|svg)')
// Caching images that ran through imagemin
.pipe(cache(imagemin({
interlaced: true
})))
.pipe(gulp.dest('src/images/'));
});
gulp.task('images-dist', function () {
return gulp.src('src/images/**/*.+(png|jpg|jpeg|gif|svg)')
// Caching images that ran through imagemin
.pipe(cache(imagemin({
interlaced: true
})))
.pipe(gulp.dest('dist/images/'));
});
gulp.task('fonts', function () {
return gulp.src('src/fonts/**/*')
.pipe(gulp.dest('dist/fonts'));
});
gulp.task('clean:dist', function () {
return del.sync('dist');
});
gulp.task('build', function (callback) {
runSequence('clean:dist', ['sass-dist', 'useref-dist', 'images-dist', 'fonts', 'views-dist'],
callback
);
});
gulp.task('default', function (callback) {
runSequence(['views', 'sass', 'browserSync', 'watch'],
callback
);
});
When I run the build task gulp build, all is well, except the relative/absolute paths inside the outputted CSS files, and the JS that runs the final product, whereas fonts/backgrounds/icons and JS functionality is not translated into the final build.
What is wrong with my Gulp file, and how can I fix it?

Gulp watch task with Browsersync with Jekyll does not propagate modified content

When calling gulp the site and its assets are generated correctly once. The watch tasks start, but they never register new changes nor refresh the browser with Browsersync.
My goal is to have a full automation in the build process. For example, if _config.yml changes Jekyll will rebuild itself. Same idea applies to every file.
What I have tried so far:
Creating separate gulp.watch tasks for build:scripts, build:styles, build:images and build:jekyll.
Calling .on('change', browserSync.reload) on every separate gulp.watch task
Creating .pipe(browserSync.reload({stream: true})) in build:styles, build:images, build:scripts and build:jekyll
Here are the contents of gulpfile.js:
'use strict';
var autoprefixer = require('gulp-autoprefixer');
var browserSync = require('browser-sync').create();
var concat = require('gulp-concat');
var del = require('del');
var gulp = require('gulp');
var imagemin = require('gulp-imagemin');
var rename = require('gulp-rename');
var run = require('gulp-run');
var runSequence = require('run-sequence');
var sass = require('gulp-sass');
var uglify = require('gulp-uglify');
gulp.task('build:styles', function() {
return gulp.src('_assets/styles/main.sass')
.pipe(sass({
outputStyle: 'compressed'
}))
.pipe(autoprefixer({
browsers: ['last 4 versions']
}))
.pipe(rename('main.min.css'))
.pipe(gulp.dest('assets/styles'))
.pipe(browserSync.stream());
});
gulp.task('build:scripts', function() {
return gulp.src('_assets/js/*.js')
.pipe(concat('main.js'))
.pipe(uglify())
.pipe(rename('main.min.js'))
.pipe(gulp.dest('assets/js'))
.pipe(browserSync.stream());
});
gulp.task('build:images', function() {
return gulp.src('_assets/img')
.pipe(imagemin())
.pipe(gulp.dest('assets/img'));
});
gulp.task('build:jekyll', function(callback) {
// --incremental regeneration doesn't update front matter
var shellCommand = 'jekyll build';
return gulp.src('')
.pipe(run(shellCommand))
browserSync.reload();
callback();
});
gulp.task('clean', function() {
return del(['_site', 'assets']);
});
gulp.task('build', function(callback) {
return runSequence('clean', ['build:scripts', 'build:styles', 'build:images'], 'build:jekyll', callback)
});
gulp.task('watch', ['build'], function() {
browserSync.init({
server: {
baseDir: '_site'
},
open: true
});
gulp.watch(['_config.yml' ,
'*.html', '_layouts/*.*',
'_pages/*.*', '_assets/**/**/*.*'],
['build']).on('change', browserSync.reload);
});
gulp.task('default', ['watch']);
Why would Browsersync and Jekyll register the changes correctly?

I have managed to get Browsersync see all the changes in the needed files and reload browser with the following gulpfile.js tasks:
'use strict';
var autoprefixer = require('gulp-autoprefixer');
var browserSync = require('browser-sync').create();
var concat = require('gulp-concat');
var del = require('del');
var gulp = require('gulp');
var imagemin = require('gulp-imagemin');
var rename = require('gulp-rename');
var run = require('gulp-run');
var runSequence = require('run-sequence');
var sass = require('gulp-sass');
var uglify = require('gulp-uglify');
gulp.task('clean', function() {
return del(['_site', '.publish', 'assets']);
});
gulp.task('build:scripts', function() {
return gulp.src('_assets/js/*.js')
.pipe(concat('main.js'))
.pipe(uglify())
.pipe(rename('main.min.js'))
.pipe(gulp.dest('assets/js'));
});
gulp.task('build:styles', function() {
return gulp.src('_assets/styles/main.sass')
.pipe(sass({
outputStyle: 'compressed'
}))
.pipe(autoprefixer({
browsers: ['last 4 versions']
}))
.pipe(rename('main.min.css'))
.pipe(gulp.dest('assets/styles'));
});
gulp.task('build:images', function() {
return gulp.src('_assets/img')
.pipe(imagemin())
.pipe(gulp.dest('assets/img'));
});
gulp.task('build:jekyll', function(callback) {
// --incremental regeneration doesn't update front matter
var shellCommand = 'jekyll build';
return gulp.src('')
.pipe(run(shellCommand));
callback();
});
gulp.task('build', function(callback) {
return runSequence('clean', ['build:scripts', 'build:styles', 'build:images'], 'build:jekyll', callback)
});
gulp.task('rebuild', ['build'], function(){
browserSync.reload();
});
gulp.task('default', ['build'], function() {
// maybe important (injectChanges: true)
browserSync.init({
server: {
baseDir: '_site'
},
open: true
});
gulp.watch(['_config.yml' ,
'*.html', '_layouts/*.*',
'_pages/*.*', '_assets/**/**/*.*'],
['rebuild']);
});

Css stylesheet has the wrong path when using gulp

I have been struggling for a while now and it is fairly frustrating to be honest.
The problem:
I created a gulpfile for my static website, and all i want to do is use browserSync, to compile sass into css and to minify the script and css files. Everything works fine, excluding one thing:
When I run "gulp" everything loads, besides de css file, which is located in "CSS/". Apparently the server thinks that the css file is ("CSS/style.css/") a folder actually.
Screenshot with the console error:
image
the css file is located in "css/style.css"
"use strict";
let paths = {
script: "js/*.js",
minifiedScript: 'script.min.js',
cssPath: "css/*.css",
productionFolder: "production",
sassPath: "scss/*.scss",
htmlFiles: "*.html"
};
const gulp = require('gulp');
const concat = require('gulp-concat');
const uglify = require('gulp-uglify');
const sourcemaps = require('gulp-sourcemaps');
const del = require('del');
const browserSync = require('browser-sync').create();
const cssMin = require('gulp-css');
const sass = require('gulp-sass');
const inject = require('gulp-inject');
const rename = require("gulp-rename");
gulp.task('browserSync', function() {
browserSync.init({

.pipe(gulp.dest('./css'))
.pipe(browserSync.stream());
});
gulp.task('index', function () {
var target = gulp.src('index.html');
// It's not necessary to read the files (will speed up things), we're only after their paths:
var sources = gulp.src([paths.script,paths.cssPath], {read: false});
return target.pipe(inject(sources))
.pipe(gulp.dest(''));
});
gulp.task('cssMinify', function(){
return gulp.src(paths.cssPath)
.pipe(cssMin())
.pipe(gulp.dest(paths.productionFolder + "/minified css"))
.pipe(browserSync.stream());
});
gulp.task('clean', function() {
// You can use multiple globbing patterns as you would with `gulp.src`
return del(['build']);
});
gulp.task('scripts', ['clean'], function() {

.pipe(sourcemaps.write())

Error when running Gulp

I am setting up gulp for my project,and get this message when I run it.
stream.js:74
throw er; // Unhandled stream error in pipe.
^
Error: EEXIST: file already exists, mkdir
'C:\Users\Theodosios\Desktop\AngularJs

I am spending hours to see what's wrong,but I don't know what's happening. So here is my gulp code.
var gulp = require('gulp'),

browserSync = require('browser-sync'),
del = require('del'),
ngannotate = require('gulp-ng-annotate');
gulp.task('jshint', function () {
return gulp.src('app/scripts/**/*.js')
.pipe(jshint())
.pipe(jshint.reporter('jshint-stylish', {beep: true}));
});
// Clean
gulp.task('clean', function () {
return del(['dist']), del(['../json-server/public'], {force: true});
});
// Default task
gulp.task('default', ['clean'], function () {
gulp.start('usemin', 'imagemin', 'copyfonts');
});
gulp.task('usemin', ['jshint'], function () {
return gulp.src('./app/**/*.html')
.pipe(usemin({
css: [minifycss(), rev()],
js: [ngannotate(), uglify(), rev()]
}))
.pipe(gulp.dest('dist/'))
.pipe(gulp.dest('../json-server/public/'));
});
// Images
gulp.task('imagemin', function () {
return del(['dist/images']), gulp.src('app/images/**/*')
.pipe(cache(imagemin({optimizationLevel: 3, progressive: true,
interlaced: true})))
.pipe(gulp.dest('dist/images')).pipe(gulp.dest('../json-
server/public/images'))
.pipe(notify({message: 'Images task complete'}));
});
gulp.task('copyfonts', ['clean'], function () {
gulp.src('./bower_components/font-awesome/fonts/**/*.{ttf,woff,eof,svg}*')
.pipe(gulp.dest('./dist/fonts')).pipe(gulp.dest('../json-
server/public/fonts'));
gulp.src('./bower_components/bootstrap/dist/fonts/**/*.{ttf,woff,eof,svg}*')
.pipe(gulp.dest('./dist/fonts')).pipe(gulp.dest('../json-
server/public/fonts'));
});
// Watch
gulp.task('watch', ['browser-sync'], function () {
// Watch .js files
gulp.watch('{app/scripts/**/*.js,app/styles/**/*.css,app/**/*.html}',

// Watch image files
gulp.watch('app/images/**/*', ['imagemin']);
});
gulp.task('browser-sync', ['default'], function () {
var files = [
'app/**/*.html',
'app/styles/**/*.css',
'app/images/**/*.png',
'app/scripts/**/*.js',
'dist/**/*'

browserSync.init(files, {
server: {
baseDir: "dist",
index: "index.html"
}
});
// Watch any files in dist/, reload on change
gulp.watch(['dist/**']).on('change', browserSync.reload);
});
Any ideas? There is something wrong in one the pipes of node stream,but can't see where is the error.
