make: *** [Makefile:18: build] Error 2

A linha mencionada parece ser

  "use strict"; // jshint ;_;

em todos os arquivos jota-esses.

Esse string deve ser comentado com barrra dupla.

Em vez disso tentei com /* */ em um dos arquivos e deu certo.

Mas ainda tem erro que se refere à linha no bootstrap-collapse.js assim

      this.$element
        .removeClass('collapse')
        [dimension](size || 'auto')
        [0].offsetWidth
```
