help making it work

[CydGoblin]

I have this task, but even if the files is not newer it keeps passing. I think gulp-rename is the culprit, seems to work when I remove it but shouldn't it work?

gulp.task('minStyles', function(){
  return gulp.src('./src/assets/css/*.css')
    .pipe(newer('./dist/assets/css/'))
    .pipe(rename({suffix: '.min'}))
    .pipe(minifycss())
    .pipe(gulp.dest('./dist/assets/css/'));
});
