Gulp task:

var spriteData = gulp.src(path.src.sprite)
    .pipe(spritesmith({
    imgName: '../img/sprite.png',
    cssName: 'sprite.less',
    padding: 20
}));

// Pipe image stream through image optimizer and onto disk
var imgStream = spriteData.img
// DEV: We must buffer our stream into a Buffer for `imagemin`
    .pipe(gulp.dest(path.build.img));

// Pipe CSS stream through CSS optimizer and onto disk
var cssStream = spriteData.css
    .pipe(gulp.dest('src/css/blocks/'));

// Return a merged stream to handle both `end` events
return merge(imgStream, cssStream);
});
