Transpiling nodejs app with gulp-babel ignore doesn't work

I have created a task in gulp to transpile my nodejs app:

gulp.task('babel', function() {

    return gulp.src('./**/*.js')
        .pipe(babel({
            ignore: [
                './gulpfile.js',
                './node_modules/**/*.js',
            ]
        }))
        .pipe(gulp.dest('./dist'));
});

the problem is that during the transpiling the node_modules folder and gulpfile are created in the dist folder. any idea why?

gulpfile

var gulp = require('gulp');
var babel = require('gulp-babel');
var nodemon = require('gulp-nodemon');

gulp.task('babel', function() {

    return gulp.src([
            './**/*.js',
            './server/config/manifest.' + (process.env['NODE_ENV'] || 'development') + '.json',
            '!./gulpfile.js',
            '!./node_modules/**/*.js'
        ])
        .pipe(babel())
        .pipe(gulp.dest('./dist'));
});

gulp.task('start', ['babel'], function() {

    nodemon({
        script: './dist/server.js',
        ext: 'js jsx',
        tasks: ['babel']
    });
});

gulp.task('default', ['start']);

Babel's ignore just means they won't be transformed, but with that config gulp is still going to pipe them through. You probably want those patterns in an ignore option to gulp.src.

Edit: actually I forgot that the ability to exclude those patterns by passing an ignore option to gulp.src depends on how recent your glob version is (see my bug report). An alternative is the ! negated patterns @raina77ow suggested.
