gulp build task not working with Callback (cb)

Question

here is gulp file and i am using bulid task to build all files and folder directory.... so my gulp build task not working properly....

I created three task for build final build directory - bulid:cleanfolder - build:copy - build:remove

gulp build task

/******************************************
bulid task
*******************************************/

// Clear out all files and folder from bulid folder
gulp.task('build:cleanfolder', function(cb){
  del([
      'build/**'
    ], cb);
});

// task to create build Directory for all files
gulp.task('build:copy', ['build:cleanfolder'], function(){
  return gulp.src('../atoz-website/*')
  .pipe(gulp.dest('build'));
});

// task to remove unwanted file into build Directory
gulp.task('build:remove', ['build:copy'], function(cb){
  del([
      'build/assets',
      'build/gulpfile.js',
      'build/package.json',
      'build/readme.md',
      'build/.gitignore'
    ], cb);
});

gulp.task('build', ['build:copy', 'build:remove']);

problem is only bulid:cleanfolder ruining but not others tasks!

Please see my answer on Copy/Deletion in Gulp randomly gives ENOENT

You'll need to install one additional plugin:

npm install vinyl-paths

Applying this to your gulpfile would look like:

var del = require('del');
var vinylPaths = require('vinyl-paths');

// Clear out all files and folder from build folder
gulp.task('build:cleanfolder', function(){
  return gulp.src(['build'])
    .pipe(vinylPaths(del));
});

// task to create build Directory for all files
gulp.task('build:copy', ['build:cleanfolder'], function(){
  return gulp.src('../atoz-website/*')
  .pipe(gulp.dest('build'));
});

// task to remove unwanted file into build Directory
gulp.task('build:remove', ['build:copy'], function(){
  return gulp.src([
      'build/assets',
      'build/gulpfile.js',
      'build/package.json',
      'build/readme.md',
      'build/.gitignore'
    ])
    .pipe(vinylPaths(del));
});

gulp.task('build', ['build:copy', 'build:remove']);
