Why gulp-babel doesn't create any files?

Question

I want to compile my src folder to my build folder but gulp-babel doesn't create any file and I don't see any errors.

gulp.task('build', () => {
  gulp
    .src(['./src/**/*.js'])
    .pipe(
      babel({
        presets: ['@babel/preset-env']
      })
    )
    .pipe(gulp.dest('build/'))
})

Log:

[10:52:18] Starting 'build'...
[10:52:18] Finished 'build' after 5.85 ms

I got a similar source and destination for my SCSS files and it works perfectly, so it's not a path issue as far as I know.
