javascript - Gulp Task completes with no error but no file is saved to destination -

i stuck in kind of trivial issue , can not hang of it.

here scenario:

i using gulp task convert html templates javascript using gulp-html2js environment node v6.9.1, gulp 3.9.1, windows 7

here gulpfile.js

var gulp = require('gulp'); var concat = require('gulp-concat'); var html2js = require('gulp-html2js'); var sourcedir = "d:\programs_insalled\nodejs\nodeapps\myapp"  gulp.task('templates', function() {   return gulp.src( 'd:\programs_insalled\nodejs\nodeapps\myapp\templates\*.html').    pipe(html2js({outputmodulename: 'templates'})).    pipe(concat('templates.js')).    pipe(gulp.dest('d:\programs_insalled\nodejs\nodeapps\myapp\bin')); }); 

when run task, completes, in few m-sec templates.js not generated in bin directory

d:\programs_insalled\nodejs\nodeapps\myapp>gulp templates [15:28:45] using gulpfile d:\programs_insalled\nodejs\nodeapps\myapp\gulpfile.js [15:28:45] starting 'templates'... [15:28:45] finished 'templates' after 19 ms

. pipe better before pipe, give e.g of 1 of gulpile , not need put absolute machine path in dest gulpfile root path of task gulp work js use js path try inever use html2js dont know if syntax correct first try path

my e.g

 gulp.task('models', function(){         return gulp.src('models/*.*')         .pipe(gulp.dest('../dist/models'))     }); 

try you

gulp.task('templates', function() {   return gulp.src( 'templates/*.html')    .pipe(html2js({outputmodulename: 'templates'}))    .pipe(concat('templates.js'))    .pipe(gulp.dest('bin')) });
