error in compiling

[Ricp77]

Broadleaf Commerce Spring Boot React Starter 5.2.

Hi all,
from command linde I've executed the code mvn clean install from the root directory (ReactStarter-develop-5.2.x), it fauls with the error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:2.10:copy (copy-dependency) on project boot-react-starter-api: Unable to find artifact.: Could not find artifact com.broadleafcommerce:material-kit:css:1.1.1 in public snapshots (http://nexus.broadleafcommerce.org/nexus/content/groups/community-snapshots/).

How can I compile it?

Thanks in advice
