Error: "Did you forget to signal async completion? Gulp v4.0.0"

[coolemur]

When using basic example:

const gulp = require('gulp');
const download = require('gulp-download2');

gulp.task('download', () => download('http://example.com/file.jpg').pipe(gulp.dest('build')));

with gulp v4.0.0 I get error:

The following tasks did not complete: taskname Did you forget to signal async completion?

@coolemur the gulp API has changed greatly in 4.0.0 from 3.9.1. I realize you posted this quite awhile ago, but if you have a fix for gulp 4.0.0 I'd happy merge the publish a version that works with gulp 4.x

Tested with gulp 4 and it no longer appears to be an issue. Closing for now 👍
