Node.js GulpWatch添加了文件

我希望gulp跟踪文件夹中的新文件（不仅仅是文件更新）。我尝试使用

gulp.watch

和

gulp-watch

插件，这两个插件都不适用于添加新文件

我将添加我的gulp的简化版本（例如，我将只使用images文件夹）

const gulp = require('gulp');
const runSequence = require('run-sequence');

let dev = true;

// clean the build directory
gulp.task('clean', del.bind(null, ['public/build']));

// proceed and copy all images to build directory
gulp.task('images', () => {
    return gulp.src('assets/images/**/*')
        .pipe($.cache($.imagemin()))
        .pipe(gulp.dest('public/build/images'));

// build for development with watching for a changes
gulp.task('watch', () => {
    runSequence(['clean'], ['images'], () => {
        console.log('WATCHING FOR A CHANGES');

        gulp.watch([

提供的两个选项都不适用于新添加的文件，第三个选项甚至根本不跟踪文件更改，但取决于此，它应该可以工作
