Gulp - exclude file while shortening CSS

Question

Im new for Gulp .. I was able to successfully install and combine and minimize my .js and .css files, however there is one .css file that I want to exclude - print.css

Ive followed these instructions: https://www.npmjs.org/package/gulp-ignore install gulp -ignore in my local directory and change my gulpfile.js to:

// Include gulp
var gulp = require('gulp'); 

// Include Our Plugins
var jshint = require('gulp-jshint');
var concat = require('gulp-concat');
var uglify = require('gulp-uglify');
var rename = require('gulp-rename');
var minifyCSS = require('gulp-minify-css');
var imagemin = require('gulp-imagemin');
var exclude = require('gulp-ignore').exclude;


var paths = {
  scriptsNonAuth: ['Non-Auth/javascript/*.js'],
  scriptsAuth: ['Auth/javascript/*.js'],
  stylesNonAuth: ['Non-Auth/css/*.css'],
  stylesAuth: ['Auth/css/*.css'],
};

// CSS Task - Non Authenticated
gulp.task('minify-css-non-auth', function() {
  gulp.src(paths.stylesNonAuth)
    .pipe(minifyCSS(opts))
    .pipe(concat('all.min.css'))
    .pipe(gulp.dest('Non-Auth/css'))
});

// CSS Task - Authenticated
gulp.task('minify-css-auth', function() {
  gulp.src(paths.stylesAuth)
    .pipe(minifyCSS(opts))
    **.pipe(exclude('Auth/css/print.css'))**
    .pipe(concat('all.min.css'))
    .pipe(gulp.dest('Auth/css'))
});

In my CSS - Secure task, I included .pipe (exclude ('Secure / css / print.css'))

When I run gulp minify-css-secure, the task ends, but after checking the new all.min.css, I also do not see the contents of print.css inside.

, . , :

• css ( print.css)
• concat , print.css, all.min.css
• all.min.css print.css

StreamQueue. (source)

var streamqueue = require('streamqueue');

var paths = {
  scriptsNonAuth: ['Non-Auth/javascript/*.js'],
  scriptsAuth: ['Auth/javascript/*.js'],
  stylesNonAuth: ['Non-Auth/css/*.css'],
  stylesAuth: ['Auth/css/*.css', '!Auth/css/print.css'],
};

gulp.task('minify-css-auth', function() {
  return streamqueue({ objectMode: true },
    gulp.src(paths.stylesAuth)
        .pipe(minifyCSS(opts))
        .pipe(concat('all.min.css')),
    gulp.src('Auth/css/print.css'))
        .pipe(minifyCSS(opts))
  )
   .pipe(gulp.dest('Auth/css'))
});

, gulp -ignore. Gulp . .
:

stylesAuth: ['Auth/css/*.css', '!Auth/css/print.css']
