Skipping Tasks Listed as Dependencies in Gulp -

i have looked on documentation , npm try find solution this, have had no luck. have option skip tasks list dependencies when running specific task. example, if have following:

gulp.task('prerun', function(){   // cleaning, installation, etc. });  gulp.task('run', ['prerun'], function(){   // stuff });  gulp.task('watch', function(){   gulp.watch('glob/glob/**', ['run']); }); 

i able have gulp.watch execute run without having touch overhead involved in prerun. @ possible in gulp?

what's helper task? use approach eliminate dependencies in watch tasks. example can this:

gulp.task('prerun', function(){     // cleaning, installation, etc. });  gulp.task('run', ['prerun'], function(){     gulp.start('run-dev'); });  gulp.task('run-dev', function() {     // run stuff });  gulp.task('watch', function(){     gulp.watch('glob/glob/**', ['run-dev']); }); 

the prerun task can use dependency watch task if needed:

gulp.task('watch', ['prerun'], function(){     gulp.watch('glob/glob/**', ['run-dev']); });
