Gulp - Can't run tasks sequentially. What could be wrong?

Question

Node.js

Task:
1. Make an assembly to the build folder
2. Copy some files from build to the specified folder.
When I run these tasks in turn manually - everything works

gulp build
gulp copy

When I try to run sequentially - copying is not performed.

const runSequence  = require("run-sequence");
gulp.task('default', function(cb) {
    return runSequence(
        'build',
        'copy'
        cb
    );
});

What could be the reason? What can help?

Answer 1

in the build and copy tasks, you must definitely do a return. It signals that the task is over (returns a Promise) and you can execute the next one synchronously
. In general, in all feng shui tasks, you need to do return

gulp.task('copy', function () {
    return gulp.src('src/**/*.*')
        .pipe(gulp.dest('public'))
    ;
});
