Unable to deploy Azure Function in Java onto Azure cloud

Question

I have been trying to deploy an Azure function I developed in Java and built using Maven. But running the command mvn azure-functions:deploy does not work. Even though I have configured proxies on my system, it fails to get deployed and ends with the error below.

Some other points:

It's a free account
Commands like mvn azure-functions:package and azure-functions:run are successful

Failed to execute goal com.microsoft.azure:azure-functions-maven-plugin:1.4.1:deploy (default-cli) on project satya: java.net.UnknownHostException: No such host is known (management.azure.com)

I am not sure where I am going wrong.

@ThiagoCustodio: I am not sure about zip deployment. Should I create a function app first in azure portal? — Satya Panigrahy

mvn azure-functions:deploy is mainly used for the first time a function is deployed, because it produces the necessary files. It will generate random resources, by design.

Take a look of this:

https://docs.microsoft.com/en-us/azure/azure-functions/functions-create-first-java-maven?pivots=java-build-tools-maven#deploy-the-function-to-azure

Using mvn azure-functions:deploy should not cause a problem. Have you set something in pom.xml? There shouldn't be any - characters in the storage account name.

This is my pom.xml, and it has no issues:

In most cases, you should use func azure functionapp publish <FunctionAppName> to deploy function apps. First, create a FunctionApp on Azure, and then deploy to this App. Here are the docs:

https://docs.microsoft.com/en-us/azure/azure-functions/functions-run-local?tabs=windows%2Ccsharp%2Cbash#publish

By the way, have you set the same function name? If it still doesn't work, please post your pom.xml file.
