Issues while running Azure Functions with SpringBoot using maven

In addition to my comments, I fixed the issue by installing the Azure Functions Core Tools from this document, as shown in the image below.

I tried the sample code below with an HTTP trigger function in Java.

Code :

Function.java :

package com.function;

import com.microsoft.azure.functions.ExecutionContext;
import com.microsoft.azure.functions.HttpMethod;
import com.microsoft.azure.functions.HttpRequestMessage;
import com.microsoft.azure.functions.HttpResponseMessage;
import com.microsoft.azure.functions.HttpStatus;
import com.microsoft.azure.functions.annotation.AuthorizationLevel;
import com.microsoft.azure.functions.annotation.FunctionName;
import com.microsoft.azure.functions.annotation.HttpTrigger;

import java.util.Optional;

public class Function {
    @FunctionName("HttpExample")
    public HttpResponseMessage run(
            @HttpTrigger(
                name = "req",
                methods = {HttpMethod.GET, HttpMethod.POST},
                authLevel = AuthorizationLevel.ANONYMOUS)
                HttpRequestMessage<Optional<String>> request,
            final ExecutionContext context) {
        context.getLogger().info("Java HTTP trigger ran successfully.");
        final String query = request.getQueryParameters().get("name");
        final String name = request.getBody().orElse(query);

        if (name == null) {
            return request.createResponseBuilder(HttpStatus.BAD_REQUEST).body("Provide a name to get request").build();
        } else {
            return request.createResponseBuilder(HttpStatus.OK).body("Hello, " + name).build();
        }
    }
}

local.settings.json :

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "<storage_conne>",
    "FUNCTIONS_WORKER_RUNTIME": "java"
  }
}

Run Command :

mvn clean package
mvn -e azure-functions:run 
          (or)
mvn azure-functions:run

Output :

The following HTTP trigger function in Java ran successfully, as shown below:
