Azure Web Deployment Fails - Website with given name already exists - azure

Question

When deploying my application I receive the following error: Website with given name azuredemo already exists.
I am attempting to deploy a Java Spring Boot web application to Azure. I created a Spring Boot application that works on my local machine against port 80.
I then ran mvn azure-webapp:config and configured the Application and then ran config a second time to configure the Runtime.
I get the following output from maven:
AppName : azuredemo
ResourceGroup : azuredemo-rg
Region : eastus
PricingTier : Basic_B1
OS : Linux
Java : Java 11
Web server stack: Tomcat 9.0
Deploy to slot : false
Then I ran the command mvn azure-webapp:deploy to deploy the application to Azure.

So to troubleshoot the issue, I delete all of the Application Services. I deleted all of the Resource Groups. And attempted the deployment again to the same error.
I understand I am probably missing something, but going through the portal and dashboards, I cannot find what the conflict is.

Answer 1

The name of Azure App Services are required to be globally unique. Presumably, someone else has already created a web app with the name 'azuredemo'. Try making the name more unique and publishing again.

Answer 2

In my case I wanted to update an app with a new deploy. If you get the error in this situation like I did, make sure that the resource group name matches the one that is already added in azure.
