This request works properly from windows batch but i cannot run using azure java sdk. I'll appreciate any feedback about how to run this command using azure java sdk

azure java sdk for az get token programatically:-

You can use the below java spring-boot code to retrieve the access token and it worked for me as follows.

RestApiController.java

package com.myapp.restcall.controller;  
import java.util.Collections;  
import org.json.JSONObject;  
import org.springframework.http.HttpEntity;  
import org.springframework.http.HttpHeaders;  
import org.springframework.http.HttpMethod;  
import org.springframework.http.MediaType;  
import org.springframework.http.ResponseEntity;  
import org.springframework.util.LinkedMultiValueMap;  
import org.springframework.util.MultiValueMap;  
import org.springframework.web.bind.annotation.GetMapping;  
import org.springframework.web.bind.annotation.RestController;  
import org.springframework.web.client.RestTemplate;  
  
@RestController  
public class RestApiController {  
  
   @GetMapping(value = "/gettoken")  
   public static String getToken() throws Exception {  
   String url = "https://login.microsoftonline.com/<tenantID>/oauth2/token";  
  HttpHeaders headers = new HttpHeaders();  
  headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);  
  MultiValueMap<String, String> inputMap = new LinkedMultiValueMap<>();  
  
  inputMap.add("grant_type", "client_credentials");  
  inputMap.add("client_id", "CLIENT_ID");  
  inputMap.add("client_secret", "CLIENT_SECRET");  
  inputMap.add("resource", "https://management.core.windows.net/");  
  HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(inputMap,  
  headers);  
  RestTemplate template = new RestTemplate();  
  ResponseEntity<String> response = template.postForEntity(url, entity, String.class);  
  JSONObject myjson = new JSONObject(response.getBody());  
  String data = (String) myjson.get("access_token");  
  System.out.println(data);  
  String access_token = data;  
 return access_token;  
  
  }  
}

Replace CLIENT_ID, CLIENT_SECRET & TENANT_ID in the above java code before executing it.

To build the program, use below commands in the IDE terminal.

mvn clean install
mvn spring-boot:run

Token generated at localhost:8080/gettoken successfully.
