gulp-sourcemap not working after using clean css. about gulp-clean-css HOT 3 CLOSED

I don't believe you can use the api's together this way and expect the correct results. Try the following...

return gulp.src('themes/'+theme+'/css/style.less')
  .pipe(sourcemaps.init())
  .pipe(less())
  .pipe(sourcemaps.init({loadMaps: true}))
  .pipe(cleancss())
  .pipe(sourcemaps.write('./'))
  .pipe(gulp.dest('www/themes/'+theme+'/css'));
});

You need to call sourcemaps twice with the loadMaps because we're using two plugins. I'd poke around on stackoverflow or other issues - you'll see this is a common wall people hit at times.

Here is one issue that you could peek at How to use in combination with gulp-sass

Thank you scniro for your reply. but I'd already tried and unfortunately this is not working

from gulp-clean-css.

Sorry, I don't have enough info here to determine one way or another if your difficulties can be traced back to gulp-clean-css.

If you create a sample repo which clearly reproduces this issue and you tell me your expected results - I'll happily clone it and investigate.
