GTT Sales Order Service - Build error

[Badhusha]

Hi, I am trying to deploy the GTT-Salesorder-service to my BTP account. When I try to package it with maven I am getting dependency error.

I cloned the repository from GTT Github.

When I do a maven build I am getting errors like below,

The following artifacts could not be resolved: org.springframework.security:spring-security-web:jar:5.5.0-M1, org.springframework.security:spring-security-config:jar:5.5.0-M1, org.springframework.security:spring-security-core:jar:5.5.0-M1: Could not find artifact org.springframework.security:spring-security-web:jar:5.5.0-M1 in SpringFramework (https://maven.springframework.org/milestone/)
