Cannot deploy HelloWorld App to Appspot

I have been following this Udacity tutorial on how to deploy to Appspot from Eclipse EE.

https://classroom.udacity.com/courses/ud859/lessons/1215898636/concepts/14551185740923#

here are the instructions written out...

https://docs.google.com/document/d/1EO3pQ53DQP3SW4LCnOLiUtgAKCWbqXVprBWj0TOlRUM/pub

I believe I have followed it to the letter, but when I try to update the application it insists that the project does not exist and gives me a 404 error. However, if I go to Google Cloud Platform the project is there and I can see the project id.

I have,

1. Changed the application in appengine-web.xml to be the project id hello-around-the-world-155900

2. Upon prompt Granted App Engine appcfg permissions

3. Installed Google eclipse plugin and logged into Google with the same account that is the owner of the project

4. I am using jdk 1.7.0_80 and maven 3.3.9

5. Created a new App engine project and restarted my computer

Here is my appengine-web.xml

<?xml version="1.0" encoding="utf-8"?>
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
    <application>hello-around-the-world-155900</application>
    <version>1</version>
    <threadsafe>true</threadsafe>
    <system-properties>
       <property name="java.util.logging.config.file" value="WEB-INF/logging.properties"/>
    </system-properties>
</appengine-web-app>

Here is the console log,

Please see the logs [C:\Users\Joes1\AppData\Local\Temp\appcfg4148446068266547082.log] for further information.

Could someone please give advice on what I am missing? There doesn't seem to be many variables here and many people use this service so there must be an answer somewhere.

The error message says:

This application does not exist (project_id=u'845830179642'). To create an App Engine application in this project, run "gcloud beta app create" in your console.

The problem here is that you need to create an App Engine application in the GCP project to be able to deploy. You can do that with the gcloud app create command in the command line (beta is not necessary anymore), or you can go to the App Engine Dashboard in Cloud Console and create it.

See the documentation about how to create a GCP project and the App Engine application:
