各位大佬，现在我用gulp4 watch监听某个文件更改后，把我所有文件都编译了，我只想编译更改后的文件，怎么做？

Question

gulp.task('watch',function(done){

gulp.watch('src/sprites/**/*.{png,jpg}',gulp.series('sprites'));
gulp.watch('src/sass/**/*.scss',gulp.series('css'));
gulp.watch('src/images/**/*.{png,jpg,gif,ico}',gulp.series('image'));
gulp.watch('src/js/**/*.js',gulp.series('js'));
gulp.watch('es6/*.js',gulp.series('browserify'));
gulp.watch(['rev/**/*.json','src/**/*.html'],gulp.series('rev'));
done();

});

gulp.task('default',gulp.series(gulp.parallel('connect','watch','sprites','css','js','browserify','image','rev')));

gulp.watch(PATHS.entry).on('all', function(stats, path) {

         .pipe(...)
         .pipe(gulp.dest(PATHS.output));
      })
