java.lang.NoClassDefFoundError: Could not initialize class com.azure.identity.implementation.RegionalAuthority

Question

Describe the bug

We are in process of writing PT scripts (using JMeter) so that they can be executed using Azure Load test tool. As part of this project, we need to store our test login credentials in Azure key vault so that these PT scripts can read these credentials from vault during run time. To achieve this, we have written a piece of code in JSR223 preprocessor using Groovy language. But its throwing below error: 

Below is the code written in JSR223 preprocessor

import com.azure.identity.implementation.*

import com.azure.identity.DefaultAzureCredentialBuilder

import com.azure.security.keyvault.secrets.SecretClientBuilder

def SecretName = "mysecretname";

def keyVaultName = "myVaultName";

def keyVaultUri = "https://${keyVaultName}.vault.azure.net/";

def credential = new DefaultAzureCredentialBuilder().build() - Line of error

def client = new SecretClientBuilder().vaultUrl(keyVaultUri).credential(credential).buildclient()

def secretvalue = client.getSecret(SecretName).getValue()

vars.put("password",password)
