module.exports = function (gulp, config, plugins) {
    return {
        deps: [],
        params: [],
        fn: function () {
            return gulp.src('./bower.json')
                .pipe(plugins.mainBowerFiles())
                .pipe(gulp.dest('Build/libraries'));
        }
    }
};

And here is my bower.json

  },

        "dist/js/bootstrap.js",

        "dist/fonts/glyphicons-halflings-regular.woff"
      ]
    }
  }
}

this is not a gulp plugin, you should use it in this way:

return gulp.src(plugins.mainBowerFiles())
  .pipe(gulp.dest('Build/libraries'));
