What's wrong with Gulp.js?

Question

gulp.js

var gulp = require('gulp'),
    concatCss = require('gulp-concat-css'),
    minifyCss = require('gulp-minify-css'),
    rename    = require('gulp-rename');


gulp.task('main-layout-1-css', function () {
    return gulp.src([
        'static/css/base.css',
        'static/css/bootstrap.css',
        'static/css/font-awesome.min.css',
        'static/css/bootstrap-social.css',
        'static/css/all.css',
        'static/css/layout.css'
        ])
        .pipe(concatCss('main-layout-1.css'))
        .pipe(minifyCss())
        .pipe(rename('main-layout-1.min.css'))
        .pipe(gulp.dest('assets/css/'));
});

when trying to execute a task, it gives an error
events.js: 141
throw er; // Unhandled 'error' event
^
Error: undefined:910:28: missing '}'

Answer 1

I found an error in css
and had to look for it in 2k lines. Moreover, phpstorm believed that everything was fine here. Can gulp be asked to ignore this? Or pointing out exactly where the failure is. Because "Error: undefined:910:28: missing '}'" points to a position in the build file, not the source.
