Task after webdriver_standalone is not running.

[Bsunny]

I need to run following tasks one after other:

1. Webdriver-manager update
2. Webdriver-manager start
3. Run my scripts

Problem:
Task 1 ran --> after that Task 2 ran --> but Task 3 DID NOT ran...

On the command prompt, it stuck after this line.
23:08:49.060 INFO - Selenium Server is up and running

My gulp file has following:

var gulp = require('gulp');
var runSequence = require('run-sequence');
var protractor = require('gulp-protractor').protractor;
var webdriver_update = require('gulp-protractor').webdriver_update;
var webdriver_standalone = require('gulp-protractor').webdriver_standalone;

gulp.task('default', function (callback) {
    runSequence('webdriver_update', 'webdriver_standalone', 'run_scripts', function () {
            console.log('AABB');
            callback;
    });
});


gulp.task('webdriver_update',webdriver_update);
gulp.task('webdriver_standalone',webdriver_standalone);
gulp.task('run_scripts', function () {
    gulp.src(['./specs/LoginPage/*specs.js'])
        .pipe(protractor({
            configFile: "conf.js"
        }))
        .on('error', function(e){
            throw e
        });
});

It appears that your tasks aren't configured correctly for asynchronous processes. Please read the documentation.

If the tasks don't return something (promise, stream, callback), or they never complete, then run-sequence cannot determine when to start the next task.

It is 'webdriver_standalone' task that is not returning anything. Can you please help me to make it return, what code should I write ?

This is then a Gulp or webdriver issue, not run-sequence. run-sequence simply asks gulp to run the specific tasks. It listens for a task to end before starting the next. If a task never ends, then it cannot start the next one.
